I am merely posting this in ase it is more than a coincidence.
Testing yesterdays WIndows updates on my Win 7 Pro 64 bit with PGP WDE client from Universal Server 3.2.0 MP1 (Build 1950), I get a blue screen immediately following the Win 7 splash screen.
It may very well just be a coincidence.
I just wanted to post this in case anyone else runs into it, someone else has noted it here.
