I am on the 22449.1000 rs_prerelease (Windows Insider Program - dev channel member). I have this issue where Desktop Window Manager sometimes uses up all the available RAM and the PC crashes. Restarting the PC helps momentarily until after a long while, dwm.exe acts up again and ram usage just endlessly increases until 100% memory is used. I have also noticed that dwm.exe uses GPU 0 - 3D for the GPU engine (which is my cpu) and the power usage is always "Very High."

 

I tried the following approaches:

1. Update/reinstall both cpu and gpu drivers.

2. Open command prompt as administrator and run 

sfc /scannow

Neither of these fixed the issue.

 

Please help me. This issue is affecting my workflow A LOT. I like Windows 11 so far, it's really a shame that this is happening.
