I Installed 5219 and I figured I would share my thoughts on it. First of all, I think someone at MS screwed the DWM subsystem, laggy as all hell on an AMD 64 3200+ @2.5 GHz with a Geforce 6800GT.

Audio tends to cut out when the system is under load but I THINK it has something to do with the System Maintenance Service, If I disable that service it doesn’t seem to do it. A good way to test is to get an MP3 going and start playing a game of chess, the sound will cut out on the MP3 from time to time, if you disable System Maintenance Service it seems to go without cutting out at all. I will keep you all posted on my findings :).
