Hello I'm running on widows 10 trying to update to 22H2 but getting an error with that as well as other updates such as .net update, I've tried using SFCFIX and going through the steps on the Sysnative Forums which did not help I then tried posting on there forums but for some reason it won't let me so now I'm here any help would be much appropriated i have the DISM log, ComponentsScanner.txt and the CBS File ready if they would be useful thanks.

Please try these steps exactly.

  • Download SFCFix.exe by niemiro of Sysnative forums, and save this to your Desktop.
  • Download the file, SFCFix.zip, and save this to your Desktop. Ensure that this file is named SFCFix.zip - do not rename it.
  • On your Desktop, you should see two files: SFCFix.exe and SFCFix.zip. Drag the file SFCFix.zip onto the file SFCFix.exe and release it. See illustration image
  • When you see the prompt "Will you allow SFCFix to communicate with Sysnative servers?", type "n" for no. Press Enter to continue.
  • SFCFix will now process the script. It will take some time to complete. Upload the output file SFCFix.txt.
  • Restart Windows and run the following command from Command Prompt (admin):
DISM.exe /Online /Cleanup-image /Restorehealth

Post the DISM output here.

    Hi,

    Please share the DISM log, ComponentsScanner.txt, and the CBS folder (zipped) on OneDrive or GoFile.io, and post the link here.

    Note that the SFCFix package created for another user will not work on your system because it's customized.
