## What it is
A small C utility that cold-patches the Windows 11 Desktop Window Manager (uDWM.dll) to disable window rounded corners, and can restore them by running again. It downloads symbol files during patching and backs up the original DLL for recovery.

## Use cases
- disable rounded window corners in Windows 11
- restore square window corners on Windows 11
- patch dwm uDWM.dll to remove rounded corners

## When to choose
