Grrrrrr..... Windows update kb2803821 really screwed everything up. Apparently messed up things with my registry. No info even shows up in system information. I keep trying to do system restore and it won't restore - I get transient error 0x800423F3. I try to restore via safe mode and same thing. I try to reboot via the Last Known good start and it doesn't work. I've been trying to find info on this but nothing seems to work. I HAVE TO GET THIS LOUSY UPDATE OFF MY COMPUTER and restore it to before it updated! How do I do this?
