This is really unnecessary and more placebo than helpful, not to mention old:

If you want to reduce input lag for exclusive fullscreen, turn off “fullscreen optimizations”. But that specific bug, introduced in build 1903, was fixed a few years ago. (But if you still somehow get it — you can just turn this off per-game instead of this wide hack!)
Modern DXGI flip presentation model doesn’t add input lag anymore and properly detects when the exclusive fullscreen app is the only one showing, and gives it direct render control. (E.g. you can frame tear again!)
I think some UIs will also just not work nowadays if you kill DWM, even more likely in Windows 11 since more UI got moved to WinUI.
