While not trying to give too much info here, I NEVER install (let Microsoft install whatever they want) via automatic update. Most of it is bloatware that's really not needed. I'm not going into any detail on the subject, but if you really want to know, they usually don't tell you what update #2555307935144 is for anyway. Most of the stuff has always been 3rd party. I don't like that. I install what I want. To do this you have to spend time on M$ forums (technet) that involves a LOT of reading. Critical updates are really all that's needed. But that's my way of updating.
