Have you ever gotten up in the morning and sat down at your computer, only to discover that it had rebooted itself during the night because of Windows Update - and all those documents and web sites you had spread across the desktop and were working on are now gone? Grrr. Well, there is a way to prevent this from happening, at least with some versions of Vista (we've heard that it doesn't work with Home, but haven't had a chance to test that). It does work with Ultimate and Business editions. The fix involves editing the registry, so be careful and back it up first. Here are the steps:
- In your registry editor, navigate to the following key: HKEY_LOCAL_MACHINE \ SOFTWARE \ Policies \ Microsoft \ Windows \ WindowsUpdate \ AU
- Right click an empty space in the right pane and click New, then select DWORD value.
Name the new value NoAutoRebootWithLoggedOnUsers
- Set the value data field to 1.
- Close the registry editor.
Now you don't have to worry about the OS shutting down when you least expect (and least want) it to.
