Hey guys,sorry for the double posts but a question for rik or anyone else who has used the SFC /Scannow tool i found out more info on the PC in question and wanted to check something before continuing.The PC originally came pre installed with Windows XP home SP1 since then lots of windows updates have been installed but not SP2.If i use SFC will i encounter any issues since i assume some files that will be replaced could be different then whats on the CD thanks to the updates?
