It drives me up the wall when Windows Automatic Update downloads and installs new updates after I leave work and then goes ahead and restarts my system. I came in this morning to a new Windows session. I had quite a few programs running when I left the office which I now need to re-open and find my place again. I know that Microsoft is doing this for security reasons, but it still drives me nuts.
Anyway, if you want to change the settings for Automatic Updates then go to the control panel and look for the icon titled "Automatic Updates". You can then choose to have the updates downloaded but not automatically installed or a couple of other options. For my work system, I've chosen to select "Notify me but don't automatically download of install them.".
