Unless you did something weird, that error of not being able to use a keyboard just popped up on a lot of XP home right after the first of the month. I mylef, and in the middle of trying to fix it, as after I finally got the keyboard to work, before using nlite, I know get the stop code 7b error. (I know three people that all have the problem - as support is telling them to do a total restore. I stopped them.) If I get it working I will post it here. If you did something to make it not work, please ignore.
