Download AMD’s new driver now to fix a major Windows 11 bug

A day after Windows 11 launched, AMD posted a notice about two severe bugs that could tank performance as much as 15%. The two issues are resolved now. One fix comes from AMD, while you can obtain the other through Windows Update.

The AMD update is focused on UEFI CPPC2, or in practical terms, AMD’s preferred core feature. The Windows 11 bug wouldn’t put the most demanding work on the fastest core, leading to decreased performance overall. You can download the chipset driver update now (revision 3.10.08.506) from AMD’s website. As a reminder, this update is relevant to all AMD processors that work with Windows 11.

Microsoft just released a patch for the issue that many Windows 11 users are concerned about that can reduce gaming performance as much as 15%. This bug is related to increased L3 cache latency. It’s the lowest level of cache on the CPU, and increased latency means it clogs up data flowing into the CPU and up to the higher levels of cache.

Originally, Windows 11 could nearly double the latency of the L3 cache. Microsoft issued a patch for Windows 11 on its normal Patch Tuesday, and we hoped to see the problem resolved. But the update made the L3 cache latency issue worse, more than tripling the latency in some processors.

Microsoft issued a patch fixing this issue to Windows Insiders on October 15. Now, the patch is rolling out to the general public. To update, use Windows Key + S, search for Windows Update, and select Check for Updates. The build that fixes this issue should be available (KB 5006476). The update is all the more important considering Intel’s upcoming 12th-gen Alder Lake launch. These processors are said to work best on Windows 11, but bugs meant AMD was entering the fight at a disadvantage.

If you have an AMD processor that works with Windows 11, you should install the new patch now. Ryzen 2000, 3000, 4000, and 5000 chips are affected, as well as Threadripper 2000 and 3000, select EPYC server processors, and select Athlon processors.

After downloading the update, AMD recommends users with Zen+ or Zen 2 CPUs (Ryzen 2000 and 3000) set the AMD Ryzen Balanced power plan in the power options. To do that, open the Control Panel, select Power Options, then select Choose Power Plan. You can change your plan there.

Needless to say, Windows 11 isn’t off to a perfect start. However, these two new patches fix two of the biggest problems with the operating system. Microsoft recently released Android apps to Windows Insiders, too, delivering on one of the biggest promises for the new OS.

If you use a VPN, don’t skip this important Windows 11 update

It's not you; Windows is causing the issues this time. If the VPN on your Windows 11 or Windows 10 computer is having a hard time connecting, it is likely because of Microsoft's April security updates for Windows 11 (KB5036893 for) and Windows 10 (KB5036892), which have been reported to be the cause of the problems.

But there's good news. According to Microsoft, a patch is now available to fix the VPN problems users are experiencing.

A massive Windows 11 AI feature may launch next week despite privacy concerns
Privacy settings in Windows 11.

Windows 11 continues to build a large toolset of AI features, but the one rumored to soon launch may be the biggest change yet -- especially when it comes to your PC's privacy. Windows Latest reports that in Build 26212, the Windows 11 AI integration is named Recall and can be found on the Privacy & Security page in settings (via Albacore on X).

The concern is due to its privacy toggle. According to the latest build, you can record everything on your screen to help you better find something you were working on or searching for. The positive side is that it can help you find the report you edited when you can't remember where you saved it by accessing the timeline interface. It will also help users with their browsing history. For example, if you searched for how to use WhatsApp Web, but can't remember which browser you used or what site the information was on, AI Explorer (or Recall, as it may be named) can find the information for you.

Windows 11 may bring Live Tiles back from the dead — sort of
windows 8 1 everything you need to know live tiles

The latest Windows 11 Canary build 26212 has quietly introduced support for what is being called "Start Menu Companions." These are small widget-like apps designed to appear alongside your pinned apps or the "All apps" list in the Start Menu.

By the looks of it, these companions would offer at-a-glance information such as weather updates, stock prices, and more. And yes, they share a lot in common with the now-defunct Live Tiles feature from previous versions of Windows. They lack the bright colors and blocky shapes, but they would function in a very similar way.
