I see they aren't only for W8. I checked my w7 Ult. install & only need 15 updates = 45MB after the 1 that installed this AM also.
My Server 2012 says it has 22 important updates available, none the size of 130 MB or 200 MB Edit: The total size of all updates is 304.3 MB (WS12+Office15+VS2012)
Just got all of my updates for today, 98 MB in total. No problems here. everything is still working great. You know this has got to the first time that I've ever been able to stay fully up to date with any Windows OS ever.
its called patch Tuesday, its always the 2nd Tuesday of the month and its for all OS that Microsoft still support
