I (ghetto fix):
obviously, this only works if your computer is in a safe spot.
Boot up @ 1AM (and if on, just stay on).
ALWAYS restart after power out
AUTO-login (cmd as admin -> "control userpasswords2") (uncheck "user must login to use comp)
set the correct shortcuts into the "Startup" folder.
i like to log in manually for certain reasons, its just that i recently reinstalled w7 and forgot to change the setting for auto updates.
