I wrote a small batch file to solve the "Unable to restore DWM" error.

If error occurs, run this.zip Solution provided by @Markichu . "I encountered this and to fix it I deleted uDWM_win11drc.bak in C:\windows\system32 and rerun the exe." Originally posted by @Markichu in https://github.com/valinet/Win11DisableRoundedCorners/issues/35#issuecomment-1156041456 It's a batch file that delete uDWM_win11drc.bak . That's it. Should work.

For the sake of anyone who'd have preferred to copy-paste to their own bat file, here's the script:

cd /d C:\Windows\System32
del uDWM_win11drc.bak
pause
