    Default Tip: SFC /scannow Repairs Windows Files the Easy Way

    SFC /scannow is a super-useful command you can use in any Windows version since Windows 2000. When the SFC (System File Checker) command is used with the /scannow switch, the tool will scan all of the important Windows files on your computer and replace them as necessary.



    Missing and corrupt operating system files (like many DLL files) are arguably the biggest cause of major Windows issues. Considering that, plus the fact that SFC /scannnow is completely automatic and very easy to use, the tool should usually be one of your first troubleshooting steps.

    Use SFC /scannow to Repair Protected Windows Files

    When I ran sfc /scannow I found many files needing to be replaced. Problem was it asked for the xp sp3 disk. I upgraded to sp3 via windows update. Any thoughts, anyone?

    Hello,

    Download the ISO image from here Download details: Windows XP Service Pack 3 - ISO-9660 CD Image File and burn it to a disk using The Official ImgBurn Website or just use SlySoft Virtual CloneDrive

    Hope this helps,
    Captain

    I appreciate the input Captain. I downloaded the ISO file and burned it to a CD. I ran sfc /scannow and when instructed I inserted the CD. The response was that this was the incorrect CD despite the CD opening as the xp sp3 update. The sfc /scannow repeatedly repeated this scenario, always asking for the CD. I cancelled the sfc scan and let the xp sp3 disk run its course. It did a file check of its own making sure files were original and I ran windows update to make sure I didn't lose any files in the process. All looks fine. I ran sfc /scannow again just to see if the error messages reappeared and they were numerous.

    You need a Windows XP Service Pack 3 disc(Installation Media), you are using disc of SP3 that is installer of cumulative updates only.
