Well, were you able too get into your Safe mode at all? When Windows updates are downloaded and installed, they usually create a restore point of a known good configuration. Basically this will revert you back before the update occurred because it sounded like something nasty happened during that update.
Safe mode usually asks you if you would like too restore too an earlier point in time, in this case that is what we want.
It should be pretty easy too figure out, but just in case you get lost, heres a guide for you: http://www.pronetworks.org/forums/windows-...ore-t68748.html
Enjoy your stay at BC, and hope I helped!
