I have a acer laptop with windows vista! Sometimes When I turn it on it starts configuring updates it might take over thirty min to finish. And it does it at the start up before I log on and it won't let me do anything while its configuring. And if it doesn't do it at the start up, it will do it when I'm shutting it down and it won't let me shut down until its done. Can anyone tell me how to turn these automatic updates off.. oh and it doesn't ever say what updates are getting configured. THIS IS DRIVING ME CRAZY

I think this is what you're looking for -- take your computer back
