    Watch Dogs 2 got an update that included BAT file with this:
    @echo off
    @setlocal enableextensions
    @cd /d "%~dp0\..\bin"
    reg.exe Add "HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers" /v "%cd%\WatchDogs2.exe" /d "DISABLEDWM" /f
    pause

    The name of the actual file (forgot...) had "...win7" and AFAIK DISABLEDWM was a Compatibility Flag that could disable Desktop Composition Layer / Desktop Window Manager , but only in Windows 7.

    Why would Ubisoft do this? I know actually shutting down DWM service in Windows 8 and 10 results in Explorer crash, so what does this registry entry do then??? The game works fine though...
