windows vista service pack 2 has just been released and available for updates.
DIfferences I noticed is that it consumes more physical memory compared to sp1.
At start up in my 4 gb of RAM sp1 consumes 26% of physical RAM while on sp2 now consumes about 34% at start up. I don't know if this is good or bad.
Any differences that you noticed?
By the way this is on a 64bit version.
