When I set up Windows to encode a video overnight, and I wake up the next morning and the encode isn't finished because Windows decided to restart in the middle, I'm not happy. This basically means I can't use Windows to encode videos, period. (And no, setting Active Hours doesn't work, because the whole point is I want the videos to get encoded when I'm not active!)

The same applies to downloading large files, etc. I realize that updates are important, but it's even more important that I can actually rely on my computer.
