Windows 7 internal shutdown command

It looks like Windows 7 now has its own shutdown command. If you want to shutdown your computer with a timer, you can run:

shutdown.exe /s /t 3600

/s tells the command to do a shutdown (no reboot) and /t is to add a time out. So the command above is equivalent to the linux command

shutdown -h 3600

If you suddenly don't want to shutdown (or reboot) your computer, you can abort the command with

shutdown.exe /a
