Unfortunately this version consistently gives BSOD on the windows login screen.
Had to roll back to the previous version in safe mode.
(Running Win7Pro with almost all updates installed, including quite a few optional ones - I'm thinking maybe one of the optional updates could have created a compatibility issue.)
(My system is very stable; uptime is usually weeks between restarts - which are due to updates only.)
I'm a programmer myself, so I know this kind of stuff happens sometimes.
Just posting it here to let others know you can fix this by booting into safe-mode in case you happen to be unlucky like me.
