One of the things that annoys me about Microsoft is that it has created an operating system that behaves as if it is your job to service its needs rather than a tool that is supposed to serve yours.
I'm thinking specifically about updates. Windows constantly nags you to install updates (which wouldn't be necessary if they'd designed the thing properly in the first place) and then it expects you to interrupt what you're doing while it does. After you have downloaded updates it nags you to restart the computer in order to install them. Perhaps they could have designed it so you didn't have to restart the entire OS after every change? When you do shut down it won't let you switch off while it is installing updates, so you have to wait around twiddling your thumbs until it is finished.
Hey, Microsoft, it's MY computer, okay?
I just received an update to Internet Explorer 8 (which I don't even use) today. After it was downloaded, Windows nagged me twice to restart the system by popping up a window in front of what I was doing, even though I was in the middle of writing something and did not want these interruptions to my train of thought.
Fortunately there is a magic incantation you can remember to show Microsoft who's boss. It's:
net stop wuauserv
Just click Start, Run, type the magic words into the box and hit the Enter key. What it does is kill the Windows update service for the remainder of that session. Windows will nag you no longer, and your updates will be installed the next time YOU decide to restart.
