Winamp has been bothering me by not closing itself when shutting down or sleeping/hibernating and crashing on resuming after closing the laptop lid

I tried a few variations of Event log monitoring with Task scheduler but all proved unreliable

The solution was found in Group Policy by running taskkill.exe with /IM winamp.exe as a parameter in Computer Configuration > Windows Settings > Scripts (Startup/Shutdown)

if you want to test it, enter

taskkill.exe /IM winamp.exe

into the run prompt or command line while winamp is running. You will find taskkill.exe in c:\windows\system32 if you are ever looking, but since system32 is stored in the PATH variable you don’t have to locate it yourself by default
