It's supposed to help alot of plug in extras run correctly too so I read. We couldn't get some of the new stuff to run on sites a couple years ago and once we updated it, they ran right. Not sure why, maybe to interface windows to them better.
We never update it until its been out about a month.
They have updated that thing like 4 times in the last 8 mos.
Quien sabe lol (I think thats the right words)
