I’ve installed this update this morning on my main box at work. Now take this with a grain of salt. I have three betas going on this thing, Office 2007 SP1 and heaven only knows what runs on the background of the network sometimes. I had a lock up on my second session restart of the day. A quick trip to safe mode and then everything has been golden. With the real full on regular non beta release said to be mid April I suggest that one may want to just wait for the real thing. But if you are crazy like me then you can find this update at the link below.
