Hello!
my computer has slowed down after the new update sevice pack 2 and every time I turn on and off the computer says that it is updating.

it starts at 3 / 3 0% and it will not go ahead and it just continue without updating, it makes it every time and as I said, my computer's speed has dropped dramatically after the service pack and it is starting to annoy me very very much!
Hope you can help me.
Thanks in advance
