If you, like me, get severely pissed off because you've left your computer running all night and you wake up in the morning to find it has restarted itself (for your protection! [fuck you, Windows]) because of updates, this is how to turn it off.

Windows XP and Vista Business
Windows Vista Home Basic or Home Premium

Windows XP and Windows Vista Business

1) Start --> Run




2) Type in gpedit.msc (you may have to tell the UAC that yes you are a big girl and it's okay to hurt the bitty computer)




3) Computer Configuration --> Administrative Templates --> Windows Components --> Windows Update




4) Double click No auto-restart with logged on users for scheduled automatic updates installations




5) Select "enable" and hit "apply"

Windows Vista Home Basic and Home Premium

1) Start --> Run




2) Type in regedit (you may have to tell the UAC that yes you are a big girl and it's okay to hurt the bitty computer)




3) Navigate: HKEY_LOCAL_MACHINE --> Software --> Policies --> Microsoft --> Windows --> WindowsUpdate --> AU




4) Double click NoAutoRebootWithLoggedOnUsers




5) Change the value to "1" (no quotes) and hit okay.
