I, too, was unable to find any winupdates.exe in my task manager. The one that uses up the second most amount for me is my Norton Anti Virus (and it also is not always the second, it jumps around from 1 anywhere to 25 and up), and I was wondering, if I end that process, does that mean that my Anti Virus goes away? I dont want to end it if it wont come back. Someone please help me out.
