Excessive ram usage in Windows 11

Hi there

Since installing the Windows 11 1/2026 update, my PC has been using an excessive amount of ram. My Desktop has 32 Gigs of ram and while sitting idle,  just looking at the desktop without having anything running and only some programs running in the background, the ram usage is about 25 gigs constant. Before the update the average usage while using my PC was around 15 to 20 gigs and that's while actively using it and having multiple programs running, including heavier things like CAD and stuff. Tried rolling back the update by booting into the recovery menu and uninstalling the update, but it didn't help.

Any Ideas on how to fix it?

    Hi, I ran both Process Explorer and RAM Map. Found out the problem was two Hyper-V virtual machines that didn't shut down correctly and just stayed running in the background. The ram usage is now normal. Thanks for the tip!

    Download and run Process Explorer (Sysinternals). Hover over high-memory processes to see detailed info. Identify any process that is consuming abnormally high memory over time.
