Automatic updates

Oh I don't know about this new computer thingie. I opted to get informed about upgrades of this and that. What I didn't opt for was when I press "postpone" the friggin thing postponed only 10 min (instead of 5) and shut the damn pc off in the middle of Dr House. No manners whatsoever. Then after rebooting it refused to connect to internet. What kind of upgrades were those? Indeed a good thing I can go back to my old and reliable pc...
