Oh Windows 7 why did you let me down???

I've been so happy with Windows 7.  It was stable, it worked quickly, it didn't do all the stuff I've grown to loathe in Vista.  However, one simple little "urgent" install later and it's all gone to hell.  It's started hanging everywhere.  Nothing works properly.

So sad.  It could have been a contender.

I guess they technically have until Thursday to fix it.
