I have Windows Repair Pro (55791-1) and I think I ran it completely, but I'm not a techie. I still keep getting "Unexpected Kernal Mode Trap" blue screen of death, and an occasional "Kmode Exception Not Handled" BSOD. Microsoft's help does not exist - what they do have is waaaay too technicle for me - I don't even understand the jargon terms and abbreviations they use. BTW, Prescan OK, Package files OK, Reparse points OK, Environment Variables OK, Windows Defender OK, Check Disc No Errors, and SFC /scannow was OK. I don't know what to do next, but buying the pro version of Windows Repair Pro hasn't helped me solve the problem
