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.

It seems these days you need 8 cores because 5-6 of them will be kept busy running someone's CPU-spinning bug.
