Hi, after great success on several pc's. i wanted square corner on my upgraded win10 machine.

After installing win11 , and executing Win11DisableOrRestoreRoundedCorners my main display of 3, went black, reboot same result. so i restored uDWM.dll, and i got graphics again. so after updating win11 to latest win11 Version 10.0.22621.1702 uDWM.dll ver 10.0.22621.1485

Executing Win11DisableOrRestoreRoundedCorners.exe, same result black main screen, with graphics on the 2 other displays. anything i can try, or log? after restoring uDWM.dll and rebooting all screens are working again.

please advice :)

How did you restore the file ? I ran into the same issue…
