Microsoft has released Windows version KB5006746 with the fix for AMD processors on Windows 11. If you’ve been dealing with the L3 caching issue on your PC, you’re going to want to install this optional update.
This update is considered a C update, which means Microsoft won’t install it on your computer automatically. Instead, you’ll need to go to Windows Update on your computer and click Check for Updates manually. Once you do that, look for the update called KB5006746 and install it.
According to Reddit user adrianturingan, the update did improve the L3 caching issue on their computer, so it appears to be working as advertised. This makes sense, as Microsoft first put this update out to Windows Insiders a few days ago, so it has had time to test it and ensure it’s doing what it’s meant to.
A Microsoft Support page reads, “Addresses an L3 caching issue that might affect performance in some applications on devices that have AMD Ryzen processors after upgrading to Windows 11 (original release).”
There are tons of other fixes and improvements in this update, but there are no security fixes since it’s considered a C update. If you’re not actively suffering from any of the issues listed on the patch notes, you can safely wait until this update becomes a B update and is installed automatically on your PC.
