Currently running Windows XP SP3 having upgraded via Windows Update from original XP. Tried to run sfc /scannow and received messages that some files needed to be replaced, asking for the XP SP3 install disk. I downloaded an ISO file of XP SP3, burned it to a CD and provided it when prompted. The disk was a compilation of updates and did not resolve the issue. In a different forum (WindowsClub) I was directed to provide a CD of XP SP3 (installation media). Can anyone provide information about how to resolve this issue / obtain an appropriate CD?1 person got this answerI do too
