Windows Update is a nightmare
First thing I do is disable windows Update when I get a new PC. It nags and nags you to install the updates and a couple of times it has shut down the machine when I've been in the middle of working on something.
Surely MS can find a better way of implementing updates silently .... and until they do it stays well and truly disabled.
P.S. I don't surf porn, warez or gambling sites so it must be safe .......
