Microsoft removes documentation for switching to a local account in Windows 11

you’re *sureyou don’t want to use a Microsoft account?? —

But most Microsoft account sign-in workarounds for Windows 11 continue to work.

One of Windows 11’s more contentious changes is that, by default, both the Home and Pro editions of the operating system require users to sign in with a Microsoft account during setup. Signing in with an account does get you some benefits, at least if you’re a regular user of other Microsoft products like OneDrive, GamePass, or Microsoft 365 (aka Office). But if you don’t use those services, a lot of what a Microsoft account gets you in Windows 11 is repeated ads and reminders about signing up for those services. Using Windows with a traditional local account is still extremely possible, but it does require a small amount of know-how beyond just clicking the right buttons.

On the know-how front, Microsoft has taken one more minor, but nevertheless irritating, step away from allowing users to sign in with local accounts. This official Microsoft support page walks users with local accounts through the process of signing in to a Microsoft account. As recently as June 12, that page also included instructions for converting a Microsoft account into a local account. But according to Tom’s Hardware and the Internet Wayback Machine, those instructions disappeared on or around June 17 and haven’t been seen since.

Despite the documentation change, most of the workarounds for creating a local account still work in both Windows 11 23H2 (the publicly available version of Windows 11 for most PCs) and 24H2 (available now on Copilot+ PCs, later this fall for everyone else). The easiest way to do it on a PC you just took out of the box is to press Shift+F10 during the setup process to bring up a command prompt window, typing OOBEBYPASSNRO, rebooting, and then clicking the “I don’t have Internet” button when asked to connect to a Wi-Fi network.

Other workarounds include using the Rufus tool to create a USB installer that will automatically bypass the Microsoft account sign-in requirement, or (for Windows 11 Pro users) indicating that you want to join the PC to a corporate domain and then not actually joining it to a domain. Setting the PC up with a Microsoft account and then signing out afterward is also still an option.

There is one workaround that has allegedly stopped working—it used to be that trying to “sign in” with a nonexistent email account would get you a local sign-in option. But as of earlier this month, according to Windows Central editor Zac Bowden, it looks like the Windows 11 setup screen will just ask you to try another email address instead.

To be fair to Microsoft, all the big tech companies want you to sign in with an account before you can use all the features of the software, but neither Apple nor Google goes as far as to mandate account sign-in to access basic functionality. Macs, iPhones, and iPads will all let you complete the setup process without signing in, though you do have to know which buttons to click. Google will allow you to use Chromebooks in guest mode, and Android phones and tablets are still usable without signing in (though this does make it more difficult to find and install apps). Microsoft’s pushiness remains unique; there’s definitely a difference between a company that would really prefer that you sign in, and one that forces you to.

iFixit says new Arm Surface hardware “puts repair front and center”

how things have changed —

Both devices make it relatively easy to get at the battery and SSD.

Enlarge / Microsoft’s 11th-edition Surface Pro, as exploded by iFixit. Despite adhesive holding in the screen and the fact that you need to remove the heatsink to get at the battery, it’s still much more repairable than past Surfaces or competing tablets.

For a long time, Microsoft’s Surface hardware was difficult-to-impossible to open and repair, and devices as recent as 2019’s Surface Pro 7 still managed a repairability score of just 1 out of 10 on iFixit’s scale. 2017’s original Surface Laptop needed to be physically sliced apart to access its internals, making it essentially impossible to try to fix the machine without destroying it.

But in recent years, partly due to pressure from shareholders and others, Microsoft has made an earnest effort to improve the repairability of its devices. The company has published detailed repair manuals and videos and has made changes to its hardware designs over the years to make it easier to open them without breaking them and easier to replace parts once you’re inside. Microsoft also sells some first-party parts for repairs, though not every part from every Surface is available, and Microsoft and iFixit have partnered to offer other parts as well.

Now, iFixit has torn apart the most recent Snapdragon X-powered Surface Pro and Surface Laptop devices and has mostly high praise for both devices in its preliminary teardown video. Both devices earn an 8 out of 10 on iFixit’s repairability scale, thanks to Microsoft’s first-party service manuals, the relative ease with which both devices can be opened, and clearly labeled internal components.

Beneath the Surface

To open the Surface Laptop, iFixit says you only need to undo four screws, hidden beneath the laptop’s rubber feet; at that point, the bottom of the machine is only attached by magnets, rather than breakable retention clips. Opening the bottom of the laptop provides easy access to the battery and an M.2 2232 SSD. Labels inside the device indicate which screws need to be removed to replace which parts, and what kind of screwdriver you’ll need to do the job; scannable barcodes also make it easier to find repair manuals and parts on Microsoft’s site. Most other parts are easy to remove and replace once the bottom of the laptop is off.

The Surface Pro’s best repairability feature remains its easily accessible M.2 2232 SSD, present under a pop-off cover on the back of the tablet. From there, things get more difficult—accessing the battery and other components requires removing the screen, which is still held in place with adhesive rather than screws or magnets. This adhesive needs to be removed—iFixit cut it away with a thin plastic tool, and closing the tablet back up securely would likely require new adhesive to be applied. Once inside, the parts and screws are still labeled clearly, but you do need to remove the entire heatsink before you can replace the battery.

iFixit uses slightly different criteria for evaluating the repairability of laptops and tablets since tablets are more tightly integrated devices. So despite the identical repairability scores, the Surface Pro remains slightly more difficult to open and fix than the laptop; iFixit is just comparing it to devices like the iPad Air and Pro rather than other PC laptops, and the Surface Pro still looks better than other tablets by comparison despite the use of adhesive.

The teardown video didn’t detail exactly why iFixit knocked points off of each device’s repairability score, though iFixit took note of the soldered-down non-upgradeable RAM and Wi-Fi/Bluetooth modules. Both devices also use way more screws and clips than something like the Framework Laptop, which could also be a factor.

We’ve been using the new Snapdragon-powered Surface devices for a few days now, and we’ll have more thoughts to share about the hardware and its performance in the coming days.

win+c,-windows’-most-cursed-keyboard-shortcut,-is-getting-retired-again

Win+C, Windows’ most cursed keyboard shortcut, is getting retired again

What job will Win+C lose next? —

Win+C has been assigned to some of Windows’ least successful features.

A rendering of the Copilot button.

Enlarge / A rendering of the Copilot button.

Microsoft

Microsoft is all-in on its Copilot+ PC push right now, but the fact is that they’ll be an extremely small minority among the PC install base for the foreseeable future. The program’s stringent hardware requirements—16GB of RAM, at least 256GB of storage, and a fast neural processing unit (NPU)—disqualify all but new PCs, keeping features like Recall from running on all current Windows 11 PCs.

But the Copilot chatbot remains supported on all Windows 11 PCs (and most Windows 10 PCs), and a change Microsoft has made to recent Windows 11 Insider Preview builds is actually making the feature less useful and accessible than it is in the current publicly available versions of Windows. Copilot is being changed from a persistent sidebar into an app window that can be resized, minimized, and pinned and unpinned from the taskbar, just like any other app. But at least as of this writing, this version of Copilot can no longer adjust Windows’ settings, and it’s no longer possible to call it up with the Windows+C keyboard shortcut. Only newer keyboards with the dedicated Copilot key will have an easy built-in keyboard shortcut for summoning Copilot.

If Microsoft keeps these changes intact, they’ll hit Windows 11 PCs when the 24H2 update is released to the general public later this year; the changes are already present on Copilot+ PCs, which are running a version of Window 11 24H2 out of the box.

Changing how Copilot works is all well and good—despite how quickly Microsoft has pushed it out to every Windows PC in existence, it has been labeled a “preview” up until the 24H2 update, and some amount of change is to be expected. But discontinuing the just-introduced Win+C keyboard shortcut to launch Copilot feels pointless, especially since the Win+C shortcut isn’t being reassigned.

The Copilot assistant exists on the taskbar, so it’s not as though it’s difficult to access, but the feature is apparently important enough to merit the first major change to Windows keyboards in three decades. Surely it also justifies retaining a keyboard shortcut for the vast majority of PC keyboards without a dedicated Copilot key.

People who want to continue to use Win+C as a launch key for Copilot can do so with custom keyboard remappers like Microsoft’s own Keyboard Manager PowerToy. Simply set Win+C as a shortcut for the obscure Win+Shift+F23 shortcut that the hardware Copilot key is already mapped to and you’ll be back in business.

Win+C has a complicated history

Win+C always seems to get associated with transient, unsuccessful Windows features like Charms and Cortana.

Andrew Cunningham

The Win+C keyboard shortcut actually has a bit of a checkered history, having been reassigned over the years to multiple less-than-successful Windows initiatives. In Windows 8, it made its debut as a shortcut for the “Charms” menu, part of the operating system’s tablet-oriented user interface that was designed to partially replace the old Start menu. But Windows 10 retreated from this new tablet UI, and the Charms bar was discontinued.

In Windows 10, Win+C was assigned to the Cortana voice assistant instead, Microsoft’s contribution to the early-2010s voice assistant boom kicked off by Apple’s Siri and refined by competitors like Amazon’s Alexa. But Cortana, like the Charms bar, never really took off, and Microsoft switched the voice assistant off in 2023 after a few years of steadily deprioritizing it in Windows 10 (and mostly hiding it in Windows 11).

Most older versions of Windows didn’t do anything with the Win+C, but if you go all the way back to the Windows 95 era, users of Microsoft Natural Keyboards who installed Microsoft’s IntelliType software could use Win+C to open the Control Panel. This shortcut apparently never made it into Windows itself, even as the Windows key became standard equipment on PCs in the late ’90s and early 2000s.

So pour one out for Win+C, the keyboard shortcut that is always trying to do something new and not quite catching on. We can’t wait to see what it does next.

Windows 11 24H2 is released to the public but only on Copilot+ PCs (for now)

24h2 for some —

The rest of the Windows 11 ecosystem will get the new update this fall.

Windows 11 24H2 is released to the public but only on Copilot+ PCs (for now)

Microsoft

For the vast majority of compatible PCs, Microsoft’s Windows 11 24H2 update still isn’t officially available as anything other than a preview (a revised version of the update is available to Windows Insiders again after briefly being pulled early last week). But Microsoft and most of the other big PC companies are releasing their first wave of Copilot+ PCs with Snapdragon X-series chips in them today, and those PCs are all shipping with the 24H2 update already installed.

For now, this means a bifurcated Windows 11 install base: one (the vast majority) that’s still mostly on version 23H2 and one (a tiny, Arm-powered minority) that’s running 24H2.

Although Microsoft hasn’t been specific about its release plans for Windows 11 24H2 to the wider user base, most PCs should still start getting the update later this fall. The Copilot+ parts won’t run on those current PCs, but they’ll still get new features and benefit from Microsoft’s work on the operating system’s underpinnings.

The wider 24H2 update rollout will also likely enable the Copilot+ PC features on Intel and AMD PCs that meet the hardware requirements. That hardware will supposedly be available starting in July—at least, if AMD can hit its planned ship date for Ryzen AI chips—but neither Intel nor AMD seems to know exactly when the Copilot+ features will be enabled in software. Right now, the x86 version of Windows doesn’t even have hidden Copilot+ features that can be enabled with the right settings; they only seem to be included at all in the Arm version of the update.

Unfortunately for Microsoft, the Copilot+ PC program (and, to a lesser extent, the 24H2 update) has become mostly synonymous with the Recall screen recording feature. Microsoft revealed this feature to the public without first sending it through its normal Windows Insider testing program. As soon as security researchers and testers were able to dig into it, they immediately found security holes and privacy risks that could expose a user’s entire Recall database plus detailed screenshots of all their activity to anyone with access to the PC.

Microsoft initially announced that it would release a preview of Recall as scheduled on June 18 with additional security and privacy measures in place. Microsoft would also make the feature off-by-default instead of on-by-default. Shortly after that, the company delayed Recall altogether and committed to testing it publicly in Windows Insider builds like any other Windows feature. Microsoft says that Recall will return, at least to Copilot+ PCs, at some point “in the coming weeks.”

Aside from the Copilot+ generative AI features, which require extra RAM and storage and a PC with a sufficiently fast neural processing unit (NPU), the main Windows 11 system requirements aren’t changing for the 24H2 update. However, there are older unsupported PCs that could run previous Windows 11 versions that will no longer be able to boot 24H2 since it requires a slightly newer CPU to boot.

another setback —

Recall will go through Windows Insider pipeline like any other Windows feature.

Microsoft

Microsoft will be delaying its controversial Recall feature again, according to an updated blog post by Windows and Devices VP Pavan Davuluri. And when the feature does return “in the coming weeks,” Davuluri writes, it will be as a preview available to PCs in the Windows Insider Program, the same public testing and validation pipeline that all other Windows features usually go through before being released to the general populace.

Recall is a new Windows 11 AI feature that will be available on PCs that meet the company’s requirements for its “Copilot+ PC” program. Copilot+ PCs need at least 16GB of RAM, 256GB of storage, and a neural processing unit (NPU) capable of at least 40 trillion operations per second (TOPS). The first (and for a few months, only) PCs that will meet this requirement are all using Qualcomm’s Snapdragon X Plus and X Elite Arm chips, with compatible Intel and AMD processors following later this year. Copilot+ PCs ship with other generative AI features, too, but Recall’s widely publicized security problems have sucked most of the oxygen out of the room so far.

The Windows Insider preview of Recall will still require a PC that meets the Copilot+ requirements, though third-party scripts may be able to turn on Recall for PCs without the necessary hardware. We’ll know more when Recall makes its reappearance.

Why Recall was recalled

Recall works by periodically capturing screenshots of your PC and saving them to disk, and scanning those screenshots with OCR to make a big searchable text database that can help you find anything you had previously viewed on your PC.

The main problem, as we confirmed with our own testing, was that all of this was saved to disk with no additional encryption or other protection and was easily viewable and copyable by pretty much any user (or attacker) with access to the PC. Recall was also going to be enabled by default on Copilot+ PCs despite being a “preview,” meaning that users who didn’t touch the default settings were going to have all of this data recorded by default.

This was the version of Recall that was initially meant to ship out to reviewers this week on the first wave of Copilot+ PCs from Microsoft and other PC companies. After security researcher Kevin Beaumont publicized these security holes in that version of Recall, the company promised to add additional encryption and authentication protections and to disable Recall by default. These tweaks would have gone out as an update to the first shipments of Copilot+ PCs on June 18 (reviewers also wouldn’t get systems before June 18, a sign of how much Microsoft was rushing behind the scenes to implement these changes). Now Recall is being pushed back again.

A report from Windows Central claims that Recall was developed “in secret” and that it wasn’t even distributed widely within Microsoft before it was announced, which could explain why these security issues weren’t flagged and fixed before the feature showed up in a publicly available version of Windows.

Microsoft’s Recall delay follows Microsoft President Brad Smith’s testimony to Congress during a House Committee on Homeland Security hearing about the company’s “cascade of security failures” in recent months. Among other things, Smith said that Microsoft would commit to prioritizing security issues over new AI-powered features as part of the company’s recently announced Secure Future Initiative (SFI). Microsoft has also hired additional security personnel and tied executive pay to meeting security goals.

“If you’re faced with the tradeoff between security and another priority, your answer is clear: Do security,” wrote Microsoft CEO Satya Nadella in an internal memo about the SFI announcement. “In some cases, this will mean prioritizing security above other things we do, such as releasing new features or providing ongoing support for legacy systems.”

Recall has managed to tie together all the big Windows and Microsoft stories from the last year or two: the company’s all-consuming push to quickly release generative AI features, its security failures and subsequent promises to do better, and the general degradation of the Windows 11 user interface with unwanted apps, ads, reminders, account sign-in requirements, and other cruft.

Windows Recall demands an extraordinary level of trust that Microsoft hasn’t earned

The Recall feature as it currently exists in Windows 11 24H2 preview builds.

Andrew Cunningham

Microsoft’s Windows 11 Copilot+ PCs come with quite a few new AI and machine learning-driven features, but the tentpole is Recall. Described by Microsoft as a comprehensive record of everything you do on your PC, the feature is pitched as a way to help users remember where they’ve been and to provide Windows extra contextual information that can help it better understand requests from and meet the needs of individual users.

This, as many users in infosec communities on social media immediately pointed out, sounds like a potential security nightmare. That’s doubly true because Microsoft says that by default, Recall’s screenshots take no pains to redact sensitive information, from usernames and passwords to health care information to NSFW site visits. By default, on a PC with 256GB of storage, Recall can store a couple dozen gigabytes of data across three months of PC usage, a huge amount of personal data.

The line between “potential security nightmare” and “actual security nightmare” is at least partly about the implementation, and Microsoft has been saying things that are at least superficially reassuring. Copilot+ PCs are required to have a fast neural processing unit (NPU) so that processing can be performed locally rather than sending data to the cloud; local snapshots are protected at rest by Windows’ disk encryption technologies, which are generally on by default if you’ve signed into a Microsoft account; neither Microsoft nor other users on the PC are supposed to be able to access any particular user’s Recall snapshots; and users can choose to exclude apps or (in most browsers) individual websites to exclude from Recall’s snapshots.

This all sounds good in theory, but some users are beginning to use Recall now that the Windows 11 24H2 update is available in preview form, and the actual implementation has serious problems.

“Fundamentally breaks the promise of security in Windows”

This is Recall, as seen on a PC running a preview build of Windows 11 24H2. It takes and saves periodic screenshots, which can then be searched for and viewed in various ways.

Andrew Cunningham

Security researcher Kevin Beaumont, first in a thread on Mastodon and later in a more detailed blog post, has written about some of the potential implementation issues after enabling Recall on an unsupported system (which is currently the only way to try Recall since Copilot+ PCs that officially support the feature won’t ship until later this month). We’ve also given this early version of Recall a try on a Windows Dev Kit 2023, which we’ve used for all our recent Windows-on-Arm testing, and we’ve independently verified Beaumont’s claims about how easy it is to find and view raw Recall data once you have access to a user’s PC.

To test Recall yourself, developer and Windows enthusiast Albacore has published a tool called AmperageKit that will enable it on Arm-based Windows PCs running Windows 11 24H2 build 26100.712 (the build currently available in the Windows Insider Release Preview channel). Other Windows 11 24H2 versions are missing the underlying code necessary to enable Recall.

  • Windows uses OCR on all the text in all the screenshots it takes. That text is also saved to an SQLite database to facilitate faster searches.

    Andrew Cunningham

  • Searching for “iCloud,” for example, brings up every single screenshot with the word “iCloud” in it, including the app itself and its entry in the Microsoft Store. If I had visited websites that mentioned it, they would show up here, too.

    Andrew Cunningham

The short version is this: In its current form, Recall takes screenshots and uses OCR to grab the information on your screen; it then writes the contents of windows plus records of different user interactions in a locally stored SQLite database to track your activity. Data is stored on a per-app basis, presumably to make it easier for Microsoft’s app-exclusion feature to work. Beaumont says “several days” of data amounted to a database around 90KB in size. In our usage, screenshots taken by Recall on a PC with a 2560×1440 screen come in at 500KB or 600KB apiece (Recall saves screenshots at your PC’s native resolution, minus the taskbar area).

Recall works locally thanks to Azure AI code that runs on your device, and it works without Internet connectivity and without a Microsoft account. Data is encrypted at rest, sort of, at least insofar as your entire drive is generally encrypted when your PC is either signed into a Microsoft account or has Bitlocker turned on. But in its current form, Beaumont says Recall has “gaps you can drive a plane through” that make it trivially easy to grab and scan through a user’s Recall database if you either (1) have local access to the machine and can log into any account (not just the account of the user whose database you’re trying to see), or (2) are using a PC infected with some kind of info-stealer virus that can quickly transfer the SQLite database to another system.

Biggest Windows 11 update in 2 years nearly finalized, enters Release Preview

24H2 update includes big changes, will be released “later this calendar year.”

Biggest Windows 11 update in 2 years nearly finalized, enters Release Preview

Microsoft

The Windows 11 24H2 update isn’t scheduled to be released until sometime this fall, but testers can get a near-final version of it early. Microsoft has released Windows 11 24H2 build 26100.712 to its Release Preview testing channel for Windows Insiders, a sign that the update is nearly complete and that the company has shifted into bug-fixing mode ahead of general availability.

Microsoft has generally stuck to smaller but more frequent feature updates during the Windows 11 era, but the annual fall updates still tend to be a bigger deal. They’re the ones that determine whether you’re still eligible for security updates, and they often (but not always) come with more significant under-the-hood changes than the normal feature drops.

Case in point: Windows 11 24H2 includes an updated compiler, kernel, and scheduler, all lower-level system changes made at least in part to better support Arm-based PCs. Existing Windows-on-Arm systems should also see a 10 or 20 percent performance boost when using x86 applications, thanks to improvements in the translation layer (which Microsoft is now calling Prism).

There are more user-visible changes, too. 24H2 includes Sudo for Windows, the ability to create TAR and 7-zip archives from the File Explorer, Wi-Fi 7 support, a new “energy saver” mode, and better support for Bluetooth Low Energy Audio. It also allows users to run the Copilot AI chatbot in a regular resizable window that can be pinned to the taskbar instead of always giving it a dedicated strip of screen space.

Other new Windows features are tied to the 24H2 update but will only be available on Copilot+ PCs, which have their own specific system requirements: 16 GB of memory, 256 GB of storage, and a neural processing unit (NPU) capable of at least 40 trillion operations per second (TOPS). As of right now, the only chips that fit the bill are Qualcomm’s Snapdragon X Plus and X Elite processors, though Intel and AMD systems with faster NPUs should be released later this year. Microsoft will maintain a separate list of processors that support the Copilot+ features.

The biggest 24H2 feature specific to Copilot+ PCs is Recall, which continually takes snapshots of everything you do with your PC so that you can look up your own activities later. This comes with obvious privacy and security risks, though Microsoft says that all of Recall’s data is encrypted on disk and processed entirely locally by the NPU rather than leveraging the cloud. Other Copilot+ features include Live Captions for captioning video files or video calls in real time and features for generating new images and enhancing existing images.

Collectively, all of these changes make 24H2 the most significant Windows 11 release since the 22H2 update came out a year and a half ago. 22H2 has served as the foundation for most new Windows features since then, including the Copilot chatbot, and 23H2 was mostly just a version number change released to reset the clock on Microsoft’s security update timeline.

Despite all of these changes and additions, the 24H2 update is still called Windows 11, still looks like Windows 11, and doesn’t change Windows 11’s official minimum system requirements. Unsupported installs will stop working on a few generations’ worth of older 64-bit x86 CPUs, though these chips are old and slow enough that they wouldn’t run Windows 11 particularly well in the first place.

For people who want to start fresh, ISO files of the release are available from Microsoft’s download page here (this is a slightly older build of the OS, 26100.560, but it should update to the current version with no issues after installation). You can update a current Windows 11 install from the Insider section in the Settings app. Microsoft says to expect the full release “later this calendar year.” Based on past precedent, it’s most likely to come out in the fall, but it will probably ship a bit early on the first wave of Copilot+ Arm PCs that will be available in mid-June.

Windows 11 24H2 goes from “unsupported” to “unbootable” on some older PCs

is anyone still reading this using a Core 2 Duo? —

New Windows version needs CPU features that became common in the late 00s.

We've installed Windows 11 on systems as old as this Core 2 Duo Inspiron tower. As of version 24H2, the OS may no longer be bootable on these systems.

Enlarge / We’ve installed Windows 11 on systems as old as this Core 2 Duo Inspiron tower. As of version 24H2, the OS may no longer be bootable on these systems.

Andrew Cunningham

Officially, Windows 11 has higher system requirements than Windows 10. But to date, once you’ve bypassed those requirement checks, there have been few consequences to running Windows 11 on old hardware. Unsupported or not, Windows 11 would run on pretty much any 64-bit PC that could boot Windows 10—we’ve run it on PCs as old as a Windows XP-era Core 2 Duo desktop.

That’s apparently changing a bit in Windows 11’s 24H2 update, which Microsoft began testing earlier this month. According to posts from a user named Bob Pony on X, formerly Twitter, the latest Windows 11 builds refuse to boot on older processors that don’t support a relatively obscure instruction called “POPCNT.” Short for “population count,” it’s used for “counting the number of bits in a machine word,” according to an explainer by programmer Vaibhav Sagar.

It’s unclear why POPCNT has become the load-bearing CPU instruction for a whole bunch of Windows components, but it looks like the Windows kernel, the system’s USB and network drivers, and other core system files now require the instruction as of Windows 11 24H2.

In modern x86 CPUs, POPCNT is implemented as part of the SSE4 instruction set. For Intel’s chips, it was added as part of SSE4.2 in the original first-generation Core architecture, codenamed Nehalem. In AMD’s processors, it’s included in SSE4a, first used in Phenom, Athlon, and Sempron CPUs based on the K10 architecture. These architectures date back to 2008 and 2007, respectively.

That effectively bars mid-2000s Intel Core 2 Duo systems and early Athlon 64-era PCs from booting Windows 11 at all, not that they officially supported it in the first place. This means the change should mainly affect retro-computing enthusiasts who spend their days making YouTube videos in the “we installed Windows 11 on a potato, let’s see how it runs” genre rather than users of actual systems. Even if you upgraded these PCs with 4 or 8GB of RAM and changed out the creaky old hard drives for SSDs, these are not PCs that will run Windows 10, Windows 11, or any modern apps particularly well.

These same retro-computing enthusiasts may also find a way around this requirement eventually. Windows 10 and 11 won’t boot on systems without SSE2 support, for example, but that hasn’t stopped people from finding a way to do it anyway.

Though Windows 11’s system requirements suggest CPU clock speed and the amounts of RAM and storage your PC has, system requirements in the modern era have become more granular and esoteric. For example, it seems as though Windows 11’s CPU requirement (an 8th-gen Intel Core CPU or newer, or an AMD Ryzen 2000-series CPU or newer) is driven at least partly by support for “mode-based execution control” (MBEC), a security feature that accelerates some of the operating system’s memory integrity protections. No CPU manufacturer is including stuff like POPCNT or MBEC in their marketing materials, but modern Windows support is increasingly dictated by these kinds of features.

The next major release of Windows isn’t due until the end of the year, but it looks like Microsoft is getting an early start. New Windows Insider builds released to the Canary and Dev channels both roll their version numbers to “24H2,” indicating that they’re the earliest builds of what Microsoft will eventually release to all Windows users sometime this fall.

New features in 24H2 include a smattering of things Microsoft has already been testing in public since the big batch of new features that dropped last September, plus a handful of new things. The biggest new one is the addition of Sudo for Windows, a version of a Linux/Unix terminal command that first broke cover in a preview build earlier this month. The new build also includes better support for hearing aids, support for creating 7-zip and TAR archives in File Explorer, an energy-saving mode, and new changes to the SMB protocol. This build also removes both the WordPad and the Tips apps.

Some of these features may be released to all Windows 11 users before the end of the year. During the Windows 11 era, it’s been Microsoft’s practice to drop new features in several small batches throughout the year.

The early change to the 24H2 numbering is a departure from last year, where Windows 11 23H2 didn’t appear publicly until the end of October. And even then, it was mostly just an update that rolled over the version number and Microsoft’s support clock for software updates—most of its “new” features had actually rolled out to PCs running Windows 11 22H2 the month before.

There are some signs that this update will be fairly significant in scope. In addition to all the features Microsoft listed, there are signs that the company is revising things like the Windows setup process that you go through when installing the OS from scratch. The current setup screens have remained essentially unchanged since Windows Vista in 2006, with only light and mostly cosmetic tweaks since then (and even in the redesigned version, window borders are still done in the Vista/7 style).

Logistically, this initial build of Windows 11 24H2 allows Windows Insider testers in the most unstable Canary channel to switch to the less unstable Dev channel without completely reinstalling Windows. Eventually, this… window will close, and the Canary channel will jump into a new series of build numbers.

Whither Windows 12?

Some news outlets and users have taken this update’s announcement as proof that the rumored “Windows 12” won’t happen this year. The existence of Windows 12, largely inferred based on rumors and stray statements from PC makers and analysts, has never been officially confirmed or denied by Microsoft.

A 24H2 update does suggest that Windows 11 will continue on for at least another year, but it doesn’t necessarily preclude a Windows 12 launch this year. Windows 10 received a 21H2 update the year Windows 11 came out and a 22H2 update the year after that (not that either came with significant new features). Microsoft could decide to rename the upcoming feature update on relatively short notice—like it originally did with Windows 11, which began as a design overhaul for Windows 10. Windows 12 might happen, or it might not, but I wouldn’t take this Windows 11 24H2 update as decisive evidence one way or the other.

AI was said to be a major focus for the hypothetical Windows 12, as it has been for the last few major Windows 11 updates. Trendforce went as far as to say that “AI PCs” running “the next generation of Windows” would need a “baseline” of 16GB of RAM, though when asked about this, a Microsoft representative told us that the company “doesn’t comment on rumors and speculation.” Trendforce also said that these AI PCs would need neural processing units (NPUs) that met certain performance standards.

To date, Microsoft hasn’t imposed any specific system requirements for Copilot or Windows’ other generative AI features, aside from 4GB RAM and 720p screen requirements for the Windows 10 version of Copilot, but this could change if more of Windows’ AI features begin relying on local processing rather than cloud processing.
