If you’re a Windows Vista or Windows 7 user, click Start, type Windows Update, and then hit Enter. (XP users should head to the Control Panel and seek out Windows Update.)
Click the Change Settings option at left. (That’s where it appears in Vista and 7; not entirely sure about XP.)
Change the setting to Download updates but let me choose whether to install them.
That’s all there is to it. Windows may still nag you about installing updates, but at least it won’t reboot without your permission.
