Windows 11’s Recall feature is already running on unsupported CPUs – and it shows why this is a bad idea

Windows 11 enthusiasts are already playing with the new – and controversial – Recall feature the OS now has in preview (for 24H2), and have got it running on current Arm-based CPUs by fudging things.

While Recall is present in the recently released preview of the Windows 11 24H2 update, Microsoft makes it clear that the feature won’t work on current PCs, as it requires a Copilot+ PC (the new name for the ‘AI PC’).

In other words, Recall needs a device with a powerful enough NPU to run it (and other new AI features in 24H2), which is currently only the new Snapdragon X chips (and AMD plus Intel CPUs further down the line).

Even those Snapdragon laptops aren’t available just yet (they will be next month), but leaker Albacore has still managed to tinker under the hood of Windows 11 24H2 and get Recall working on a current Arm processor.

Making great progress enabling Recall on current Arm64 hardware, no fancy X Elite in sight! ✨Should theoretically work on Intel/AMD too, OEMs only received Arm64 specific ML model bundles so there’s not much I can do yet.Here’s a small demo video showing off screenray 🪄 pic.twitter.com/w57fF1LxiNMay 23, 2024

You can see a video of Recall being summoned on a standard (non-Copilot+) Windows 11 PC in the above post on X (formerly Twitter). As Albacore says, it shows ‘screenray’ in action which refers to the context-sensitive mode entered when you find something using Recall and select it.

As you can see, if the search result you want is a text file, screenray presents options pertaining to what you’ll need to do – copy and paste text. Or if it’s an image, you’ll get choices to copy the picture or open it for editing in an app.

Analysis: Working as not intended

It’s pretty cool to see this feature working on a processor without the necessary strength in terms of a powerful NPU (like the new Snapdragon X silicon sports), but at the same time, it illustrates why that NPU is needed. As you probably noticed, the interaction with Recall and screenray therein looks a bit laggy here – what the NPU does is provide specific AI acceleration to ensure this process runs more smoothly.

Furthermore, the feature is still in testing within a preview build here, and that won’t help either.

Albacore even sounds hopeful about getting Recall working not just on current ARM chips, but also on existing AMD and Intel (x86) CPUs, which also can’t officially run the feature. (Again, even current-gen processors from Teams Red and Blue lack an NPU with enough raw grunt).

If that happens, we can expect a similar experience to what we see here – but it’s not possible yet anyway, as Microsoft has only provided the machine learning model bundles for Arm to laptop makers. These don’t exist for AMD or Intel CPUs yet (as there’s no need for them – Lunar Lake and Strix Point, which will drive Copilot+ PCs, are still some way off launching, but they are fully expected to debut before 2024 is out).

Ultimately, this is an interesting fudge for now, but it’s likely a bad idea to be trying to get Recall up and running on a PC it’s not intended for. Simply because there may well be scenarios where it truly bogs down – such as when you have a larger, sprawling library of snapshots piled up – and there are doubtless good reasons why Microsoft has the mentioned NPU requirement in place.

Mind you, not everyone wants Recall, anyhow: certainly not those more privacy-conscious Windows 11 users out there who have already made their feelings clear. Indeed, a privacy watchdog in the UK is already investigating Recall before Microsoft even has the functionality officially live. The result of that enquiry will certainly be interesting, and Microsoft may be worried about another scenario where a big Windows 11 feature is blocked in Europe due to more stringent data regulations.

Windows 10’s days are numbered – well, we know that, as support runs out next year (with some potentially nasty consequences) – but it seems AMD is underlining that with its incoming Strix Point APUs, at least if a fresh rumor is right.

If a well-connected person posting on Weibo is correct – this is seemingly Lenovo’s China manager, as TechSpot reports – then the release of Zen 5-based Strix Point chips will witness Team Red drop support for Windows 10 drivers.

That means these incoming APUs – a fancy term for all-in-one processors, with integrated graphics and an NPU bundled up together – will only be good for Windows 11 PCs.

The manager also estimates that the IPC (Instructions per Clock) increase for Zen 5 CPUs will be around 10%, which is notably lower than some other estimates we’ve seen thus far (which are more in the 15% to 20% area, or even slightly higher).

Naturally, as this is a rumor from Weibo – not our most favored source for speculation – heap on the seasoning with this one.

Analysis: It’s all about AI

Windows 10 is, of course, still a lot more popular than Windows 11. Indeed, Microsoft’s newer OS has struggled to attract users since it was first released, and still Windows 11 only has 26% of Windows market share going by the latest statistics from Statcounter – with Windows 10 maintaining the lion’s share.

Even in gaming, Windows 11 might be doing much better than with everyday users, but it’s still behind Windows 10 (albeit the newer platform is closing on 50% finally, according to the latest Steam hardware survey).

So why would AMD look to abandon Windows 10 early – if, indeed, this is happening? Well, for starters, Windows 10 is on its way out of the door next year, as we already noted (support ends in October 2025).

Also, as TechSpot observes, Strix Point chips are at least partly about pushing hard with AI – and getting close to 80 TOPS (trillions of operations per second). And when it comes to AI, Windows 11 is very much where it’s at – the revolutionary piece of Microsoft’s puzzle, purportedly ‘AI Explorer,’ will be introduced with the 24H2 update, and this will need those faster chips capable of pushing further with TOPS to make AI functionality run swiftly enough.

In short, we need to remember that Strix Point will be powering AI PCs and new devices that’ll have Windows 11 anyway.

Some Windows 11 users are running into trouble with sporadic stuttering issues (accompanied with audio glitches), which according to reports are related to AMD processors and the necessary TPM security required by Microsoft’s newest operating system.

Specifically, on AMD PCs, there’s an implementation of TPM which is fTPM – meaning it’s integrated in firmware, rather than on a separate TPM module – and this is what folks who are affected believe is causing the issue, finding that when it’s turned off in the BIOS, the stuttering disappears.

Unfortunately, some people don’t have the option to turn off fTPM – that switch simply isn’t present in the BIOS – so they’re out of luck on that score. The other alternative solution appears to be installing a discrete TPM module, rather than relying on the firmware integrated functionality, and this also works to fix the issue – at least according to reports. Assuming you have the ability to install a separate TPM module in your PC.

As various reports detail, on Reddit, the Linus Tech Tips discussion boards and Lenovo’s forum to point out a few which Windows Latest flagged up (not to mention Microsoft’s feedback hub), the stuttering frame rates hit at random times and last for a few seconds in some cases – longer in others – and audio is garbled at the same time.

If that should occur, say, during a crucial moment of an online game you’re about to win, that’s going to be pretty frustrating (and doubtless it’ll be a serious annoyance as part of your everyday computing life, too).

Analysis: Losing TPM on Windows 11 is possible, but is it wise?

Note that this problem also occurs on Windows 10 PCs, the difference there being that enabling TPM isn’t part of the system requirements. So, while it’s fine to turn off fTPM on Windows 10 – assuming your BIOS allows for this as noted above – on Windows 11, that comes with its own potential problems.

Now, while it is possible to install Windows 11 and then turn off fTPM, that could cause issues with things like BitLocker drive encryption, or have other side-effects, like not being able to play some games (as Windows Latest observes, Valorant is one such game – and there will likely be more in the future). The biggie, of course, is that it could also interfere with receiving Windows updates, or so Microsoft says – though updates still appear to be delivered up to now.

Essentially, turning off fTPM is something of a minefield of possible collateral damage on Windows 11, and that’s why some of those who want to get around this stuttering glitch are downgrading to Windows 10.

This issue is hopefully something both Microsoft and AMD are putting their heads together to attempt to fix, so we can keep our fingers crossed that a proper resolution is delivered in the near future. If the glitches aren’t disrupting your computing experience too much, likely your best bet is to sit tight and hope for the timely delivery of a patch.

AMD’s Wraith Prism cooler, which comes bundled with some of its latest 3rd-gen Ryzen processors (and the Ryzen 7 2700X), is suffering from a surprising problem – namely fakes of the cooling solution are floating around.

Initially, it was thought that the respected RGB stock cooler had been upgraded by AMD, and just not announced yet, when photos of a very similar-looking model to the Wraith Prism emerged over at XFastest – except this one had six heat pipes, rather than the four that the standard model has.

However, AMD quickly took to Twitter to clarify that these cooling solutions with six heat pipes are illegitimate fakes designed to look like the Wraith Prism, and that they (obviously) have not been tested and validated by AMD.

Thermal trickery

So instead of speculation about how good this six pipe cooler might be, now the speculation is about what on earth is going on here. And indeed if this cooler is bundled with an AMD CPU, could there be something amiss with the chip itself?

Obviously something shady is happening, and it raises the prospect of an operation perhaps buying OEM chips, and pairing them with the fake cooler, to sell at full retail price (or possibly even fake chips – which we’ve seen in the past with Ryzen – with the fake cooler).

Although if this is the idea, quite why the cooler would be slightly different with the additional heat pipes, well, that’s anyone’s guess (in terms of not raising the profile of this counterfeiting).

Regardless, obviously you should be careful about this new counterfeit product. While it might be tempting to think that with the two extra heat pipes, this could be a better cooling solution than the official AMD-produced Wraith Prism, if it’s been made as a third-party knockoff, there’s every chance there could be all manner of things amiss in terms of the innards. Even if externally, it looks like a good copy of the original.
