    Run these in sequence from a Elevated Command Prompt:

    Dism /Online /Cleanup-Image /StartComponentCleanup
    Dism /Online /Cleanup-Image /RestoreHealth
    SFC /scannow

    If anyone fails, run it and the one after it again.

    OK thanks guys , i just ran sfc/scannow and it said there were corrupted files that couldn't be fixed with the chkdsk/f option , any other way to fix these?

    Thank you
    SFC reported errors about files and referenced CHKDSK?
    Is that right?

    After following Ztruker's suggestion,

    Launch and elevated Command Prompt and run a Read-only Disk Check

    chkdsk C:
    *** do not add any parameters

    then run Disk Check again with the fix parameter

    chkdsk C: /f
    *** this should prompt you to schedule the check on the next boot, answer yes

    Restart your machine - Disk Check will run before Windows loads

    Try SFC again.

    The Media Creation tool checks the integrity of the download after it has been downloaded.
    It's very strange that it should be corrupted.
    Where are you saving the download to?

    First one completed successfully , second command said needs to find directory where files are located to replace corrupt files so that one gave an error .

    sfc/scannow gave a corrupt files message again as expected from the failure of the second command.

    ...second command said needs to find directory where files are located...
    These may be on the CD or the USB stick that you installed Windows from.
    If the disc isn't in the CD player or the USB isn't plugged in then the recovery files won't be found.

    (At least, I think so!)

    Tried this one multiple times, including the "f" but (minus the capital C after command ) and the corrupted files seem to never get fixed , i keep getting the same " chkdsk was unable to fix some of them" message.

    Very good point , i did copy the creation tool download on to a blank DVD but have not used it , i will post a screenshot of whats on it.


    I am just confused about the correct command . I installed Windows without a DVD or USB stick , just followed the upgrade from MS so far.

    I will try the second command again with DVD installed , hoping it works.

    Ok - there seems to be an underlying issue with the drive ... I want o be be sure that the Disk Check was run automatically when the machine was restarted.

    Please follow OPTION TWO To Create .txt file on Desktop with chkdsk Results Log in this tutorial and post the Event log info for the Check disk entries.

    Check Disk (chkdsk) - Read Event Viewer Log - Windows 7 Help Forums

    I'm not sure that the disc you have is set up correctly - it sounds as though you just copied the ISO to the disc - is that correct?
    It can still be used as a source for Dism, but the disk errors should be fixed first.
