Hi taker, I see what you mean
The XP "look" is called "Luna", and it's not working correctly.
First thing I would try is put your windows XP cd in the drive, goto Start -> Run -> type in
sfc /scannow (there is a space between sfc and /scannow)
It might take 5 minutes, or 5 hours to complete. What it does, is checks for corrupt/missing system files and replaces them with the original.
Once you've tried that, we'll go from there
