    Missing or Corrupt Files - Detected SFC Output


    My windows update, windows defender and lots of other programs including Vistart start menu refuse to work. I run the Windowsupdatediagnostic download and it tells me the SFC Output is corrupted or missing. Recently the BITS wasnt working but for some reason found the windows events log was disabled in services. I went to black vipers site and reset all of the services to a standard or safe setting. Yet I cant get anything to work. Ive been running the sfc /scannow in command prompt and it says it found problems but was unable to fix them. It says to check the log files, but when i go to open them they refuse to open and say i dont have administration privileges???

    I suddenly got BITS working recently and i swore that would have fixed everything but to no avail. I am afraid to have to to a factory refresh but the problem is I foolishly listened to microsofts suggestion in the store to upgrade this from windows 8 to 8.1 therefore it automatically deletes the windows 8.0 partition on the computer thereby erasing its original operating system with cd key....

    I have heard of ones doing a factory reset or refresh and finding since that upgrade they cant get it running without them purchasing it... GAAHHHH!

    I have done a system restore, but the last system restore was a month ago and unfortunantly that was when the system was adsactly the same as this. :/

    So right now i need to try every possible avenue I can take and want to see if its possible to do a factory refresh without it freaking out because the cd key on the bottom of the computer is for a windows 8.0 and this is the useless upgraded 8.1. I would appreciate as much help as possible.

    This is a Toshiba C55-A 5300 laptop

    Run this batch file as administrator:

    dism.bat

    Once downloaded, right click it & click Properties & unblock it.

    It takes a while to finish.
    Keep an eye on it.
    You need to because half way through you need to press a key.

    Be patient.

    Hi Mickyblue,

    Welcome to the forum

    Lets try get that sfc /scannow working,

    SFC /SCANNOW Command - Run in Windows 8

    Ok so in an elevated command prompt can you try running this :

    Code:
    Dism /Online /Cleanup-Image /RestoreHealth
    Once that is done can you then run SFC again:

    Code:
    SFC /Scannow
    Now restart
    Hope that helps

    Cheers,
    Harry

    If you have an OEM PC that came with Windows 8 preinstalled and updated to Windows 8.1, then when you refresh/reset Windows, it will reinstall Windows 8 (not Windows 8.1) from hard disk recovery partition or from recovery USB flash drive.

    If you don't have an OEM PC that came with Windows 8 preinstalled and updated Windows 8 to Windows 8.1, then when you refresh/reset Windows, it will reinstall Windows 8.1 if you have Windows 8.1 USB/DVD installation media.

    This works on a desktop if you have an ISO or dvd......definitely worth a try and you still retain W8.1.
    Start laptop then click on "Restart holding down Shift Key".
    This will bring up a "Choose An Option Screen"
    Click on "Troubleshoot"...then "Advanced Options"....then "System Image Recovery".
    This will not affect any thing other than System Image.
    Hope this helps.
