The Ryzen TPM stuttering bug is finally fixed on Windows 11

A bugged implementation of firmware-based Trusted Platform Module (or TPM), something users normally need in order to use Windows 11, has been plaguing AMD Ryzen users for some time. But finally, AMD and its motherboard partners are rolling out BIOS updates that completely patch the bug, though at the moment not all boards have received the patch.

TPM can run either in the firmware of the motherboard (where the BIOS is stored) or on its own dedicated hardware, and in order to use Windows 11 TPM must be enabled. Ryzen CPUs experienced stuttering with TPM enabled, causing AMD to recommend users disable the security feature.

Unpatched Ryzen PCs that have firmware TPM suffer from severe stutter when the TPM is doing work in the background. It’s a CPU and motherboard issue, not a Windows issue, and although the bug has existed for a while, it only became a problem when users started upgrading to Windows 11. Windows 11 requires TPM to be enabled.

The only way to fix the stuttering bug without disabling TPM is to get a hardware-based module and stick it on the motherboard. Users who disable TPM can still use Windows 11, but without future updates. Obviously, that wasn’t acceptable for the vast majority of users, which is why AMD and motherboard makers are pushing out BIOS updates that fix the bug and allow firmware-based TPM to be used without issues.

This isn’t the first issue Windows 11 has had with Ryzen processors (even the best Ryzen CPUs). Near launch, AMD warned that Windows 11 could slow gaming performance by up to 15%, for instance. Thankfully this issue, among others, has been fixed since launch.

The BIOSes that contain the bug fix have the AGESA version 1207 or 1.2.0.7 microcode. Microcode updates come directly from AMD and are sent to the company’s motherboard partners, and from there it’s up to them to distribute the new microcode in the form of new BIOS updates. This means that each individual board will get its own update, so not all motherboards have gotten or will get the new AGESA microcode at the same time.

Most motherboards have already received BIOS updates with the bug fix. According to Tom’s Hardware, many vendors such as MSI and Gigabyte have already updated nearly every single AMD motherboard they’ve ever released. But some motherboards have yet to receive an update, and there’s no telling when exactly these stragglers will finally get a new BIOS with the patch. Hopefully, every Ryzen motherboard will get an update at some point.

If you buy a new motherboard, it will likely come with the microcode update. If not, make sure to read our guide on how to update your BIOS to fix Ryzen stuttering on Windows 11.

The latest Windows 11 build has a surprising bug — it gets rid of Copilot

Microsoft has updated the support page for the Windows 11 build it released last week to reveal a rather amusing bug -- it seems to have caused some devices to automatically uninstall the Copilot app and unpin it from the taskbar.

At the time of writing, Microsoft is still working on a resolution to the issue spotted by Windows Latest, recommending affected users reinstall the app and pin it back to the taskbar manually. It looks like the bug can occur on any device if it updates to build KB5053598 from Windows 11 24H2, 23H2, or 22H2, along with Windows 10 22H2 or 21H2.

Windows 11 to simplify battery monitoring with mobile-inspired icons

Microsoft is preparing changes to its laptop battery charge indicators, which should be coming to future versions of Windows 11 in the coming months. 

The updates are set to make clear distinctions between the different battery states, such as an unplugged battery, a charging battery, or a battery with an unknown status. While all Windows 11 users are scheduled to get the new battery-level icons, Windows 11 Insiders are set to get first dibs. According to Windows Latest, Microsoft previewed the battery icons to pre-release users in a video conference in early March. This conference revealed the icon images but did not give much further information about the coming design changes, such as a release timeline.

Latest Windows 11 update slows Intel’s newest desktop processors

Microsoft's latest Windows 11 24H2 (KB5050094 and KB5051987) updates are causing some serious performance issues, especially for Intel Core Ultra 9 285K users, as Neowin reports. The updates interfere with CPU speeds when a user minimizes a program or the app is out of focus. However, older Intel processors remain unaffected.

It's reported that apps are "massively throttled," causing the CPU's clock rate to drop significantly and deteriorating overall performance. Some users have resorted to using beta BIOS or changing power settings to preserve CPU performance during background processes. The Intel Core Ultra 9 285K slowdown is causing some major headaches as the issues occur across various apps, including Prime95 and 7Zip. This suggests that the 24H2 performance issues are not limited to one app but are linked to KB 5050094 and KB5051987 updates.
