Create A Scheduled Shutdown Via Script In Windows

I often use this command to create a scheduled shutdown.  You could also use to run any program you want.

schtasks /Create /SC daily /RU DOMAIN\user-account /RP myPassword /ST 18:00 /TN Auto-shutdown1800 /TR "%windir%\system32\shutdown.exe /s /f"

Just replace your username, password, and give it a unique name.

To remove it, you can delete it by its name:

schtasks /Delete /TN Auto-shutdown1800 /F
