SCCM – Offline Servicing not updating image

By May 22, 2018SCCM, Windows, Windows 10, Windows 7

Issue:

When offline servicing a Windows 7 or 10 image in System Center Configuration Manager (SCCM) you recieve an error that it is not possible to update the image.

Reason:

The reason for this issue is that in the Registry, of the WIM file you are trying to update, the value in the SessionsPending\Excluding dword value is incorrect. The value states that a reboot is required, which is not possible for the WIM file.

Solution:

  1. Get the correct index number
    – Open an elevated Powershell console
    Dism /Get-WimInfo /WimFile:<Path+NameOfYourWim.wim>

  2. Mount the WIM image using DISM.
    Dism.exe /mount-wim /wimfile:<Path+NameOfYourWim.wim> /index:1 /mountdir:<PathOfYourMountDir>

  3. Mount the software registry hive
    reg load HKLM\MountReg <PathOfYourMountDir>\windows\system32\config\software
  4. Change the registry settins
    Open RegEdit.exe
    – Go to the following path: HKEY_LOCAL_MACHINE\MountReg\Microsoft\Windows\CurrentVersion\Component Based Servicing\SessionsPending
     
    Check if the value of the Exclusive DWORD key is 3 (this should be 0)

    Claim ownership of the SessionsPending hive

    Change permissions of the SessionsPending hive

    Change the value of the Exclusive DWORD key to 0

    Close the Registry Editor
  5. Unmount the registry hive
    Reg unload HKLM\MountReg
  6. Unmount the WIM image committing changes
    Dism /Unmount-Image /MountDir:<Path+NameOfYourWim.wim> /Commit
  7. Offline service your image in SCCM
