This happens to mine if I have an update pending, worth checking if it's an intermittent issue.

My screen keeps on coming back on rather than turning off. Got any leads on that?

So a typical large bug tracker.

Yep. This shoots me in the face at least once a week. Also two other problems:

1. The start menu latency is now so bad you have to forcibly wait 2-3 seconds before typing your search after hitting the start button. This is on a stacked E5 Xeon workstation class machine.

2. Search is crap. I can type "visual" and visual studio doesn't come up!?!?

This drives me nuts. I wouldn't even mind all of this stuff going on in the background (since it ostensibly improves stability in the long run) but for God's sake Microsoft, keep it in the background! More and more over the years cats background tasks related to updates and security are hogging my cpu or saturating my disk or internet I/O while I'm in the middle of using my computer. I'm away from my computer most of the day, but no, go ahead and run all that stuff during the three hours I want to use it, certainly don't respect the preferences I set saying that exactly that time isn't okay.

You can hear the fan from another room on my laptop!

Thanks svchost.exe!

I disabled updates, but it still does... something while I am sleeping.
