Hello, 
I installed and ran PC TuneUp and Disc Doctor on two XP computers, and now both PCs have crashed and won't boot due to a missing or corrupt registry file in system32 - I have no boot disc unfortunately - can anyone advise how to fix this? I don't have a recent enough update either - I didn't expect to be needing it :( 
Any help greatly appreciated. 
Many thanks, Kerstin
