I have the recovery console installed so I am not worried about that, I don't have to startup windows if something goes wrong. It is very real though. I don't think its serious because I can save things, but I can't open folders. very strange indeed. Its like my explorer got lost in the jungle and met that guy in the middle of it and decided never to come back out.
added note: I trekked into my jungle and found my explorer. I beat him up and he came back home and everything is groovy.
