It's possible to disable Desktop Windows Composition in Windows 8.1, disabling compulsory vsync on the desktop and thus giving you less input lag in windowed applications. This is very useful for things like graphics tablets and windowed/borderless-fullscreen/browser gaming. The method involves renaming/deleting Windows.UI.Search.dll and Windows.Shell.Search.UriHandler.dll (just once), then using Procexp to suspend winlogon.exe and then kill dwm.exe. You can restart dwm.exe by resuming/restarting winlogon.exe. Is it still possible to do this in 10? If possible, is it just as convenient to just turn dwm on and off as desired?
