Shutdown.exe.

It comes with Windows XP (and 2000, I believe.) You can set it a scheduled task.

(Hope it works in Windows ME. Honestly, I have no idea about Windows ME.)

First, search your system for the Shutdown.exe. Then, make a shortcut, and (assuming it's in C:\Windows\System32) set the Target to:

c:\windows\system32\shutdown.exe -s -t 30 -c "Shutting down in 30 seconds"


You can set the timeout for as long or short as you want.

Now set it as a Scheduled Task for whatever time you want.

Going to try and attach shutdown.exe (in ZIP form) if you don't have it. Again, I hope it works in ME.
