You can use ExitWindowsEx[^] if you have the right privileges.

I think a separate thread will be more accurate since you may want to make another loop or any ting else.

I wonder if there is a built in attribute in system.management which can access the status of the application. So far i have looked into the win32_Process namespace in root/cimv2 in WMI which may have only started or stopped values for the status attribute. Or i will need an explicit timer to poll the application?
