So I'm in a cave... murdering vampires on a quest. I'm thinking ok... this is pretty cool. Get to the final boss vampire and then skyrim crashes to desktop. I think to myself... "Well, this hasn't happened since that 4GB patch..." then my PC shuts down by itself. I was kind of freaked out until I saw windows saying it was applying a update.
So apparently, windows was kind enough to download a update and boot me out of skyrim and then restart my computer all on its own. Ugh.
