    When you mount an ISO file, open This PC to see what drive letter is for the mounted ISO. There's more details in the blue note box under step 6., but the tutorials below will show you how to download an ISO, and how to mount it.

    No. Running the DISM command will only attempt to repair your Windows image to hopefully then let SFC to be able to repair your system files it found to be corrupted.

    No, it wont erase anything. It just acts like another optical drive when mounted,

    Guys I just found out that it's my windows update that is corrupt when I click an update a message pops out saying if I want to make the following changes with this program and then nothing happens it doesn't install or anything. AndClick image for larger version when I use Windows update troubleshooter this pops out. Click image for larger version I also tried the following as well Open an administrative Command Prompt window.Type the following commands, and press Enter after each command:
    net stop cryptsvc
    md %systemroot%\system32\catroot2.old
    xcopy %systemroot%\system32\catroot2 %systemroot%\system32\catroot2.old /s
    Delete all contents of the catroot2 folder, but do not delete the catroot2 folder.
    Type the following command, and then press Enter:
    net start cryptsvc
    Exit the Command Prompt window.


    Open an administrative Command Prompt window.
    At the command prompt, type the following command:

    REGSVR32 WUPS.DLL /S
    REGSVR32 WUAUENG.DLL /S

    REGSVR32 WUWEBV.DLL /S

    Try to install updates again.


    To do this, follow these steps:

    At the command prompt, type the following commands, and press Enter after each command:


    Net stop bits
    Net stop wuauserv

    Note After you complete these steps, the BITS queue is cleared.
    Try to install updates again.


    To do this, follow these steps:
    Open an administrative Command Prompt window.
    At the command prompt, type the following command:
    takeown /f C:\Windows\winsxs\pending.xml
    Rename the c:\windows\winsxs\pending.xml path by using the following command:
    Ren c:\windows\winsxs\pending.xml pending.old

    Automatic repair also do not work

    For some reason none of this work. Please help I don't know what to do and I don't want to reformat my laptop.

    Mike,

    See if using OPTION THREE in the tutorial below to completely reset Windows Update may help. It's a bit more thorough.

    i did what the tutorial said and looks like it installed properly and when i go to windows update troubleshoot it says everything was fixed including the installing recent updates but when i use sfc /scannow it still says corrupted files where found but was unable to fix some of them and when i use dism /restorehealth it says source files could not be downloaded. So what do i do now?

    i also attached my cbs log below so maybe you guys can help me figure it out becuase i dont know how to analyze the cbs log.
