How do I know when to update and when not to? My computer works fine right now and I have heard some real horror stories about Microsoft updates. Right now I have 4 critical waiting to download. I used to download them all, whether I needed them or not. Should I keep on downloading or just basically download what I think is necessary? What about the security downloads, are they all necessary. I know this isn't a Microsoft discussion board but I really don't know who else to ask and you all seem so know so much about computers so I am sorry if I am asking a question to the wrong people in the wrong place. Like I said, you people seem to know an awful lot about computers so I trust your input.
