Windows update KB2804579 fails to install

If you are unable to install Windows Update 2804579 then please read the following:

Try the easiest thing first by typing “msconfig” (without quotes) at the start>run “open” field. Choose the middle selection “Diagnostic Startup” and press the OK button. Now try downloading the update. If the update still fails, then please follow this procedure”

  1. Open the registry editor by typing regedit at the start>run “open” field and go to the following key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\Packages

  2. Backup the Packages keys by right clicking “Packages” in the left hand column and choose “Export”. I suggest that you save the backup to your C: drive so that you can find it easily in case you run into trouble. You can undo any changes by double clicking this exported “.reg” file.
  3. Scroll down to the “Packages” in the left column. Right click and choose to “delete” any package with 2804579 in the title. For my Windows 7 computer, I had  3 instances of this title: One was in Package; Package 1; Package 3
  4. If you get a permission error that you are not allowed to delete the key, then you can download an excellent programme from Raymond.cc’s website by going here.
  5. When you launch this programme select the “Registry” tab and repeat step 3 above.
  6. Finally, close the editor and reboot your computer and go to the Windows update site to download KB2804579.

A bonus of deleting the corrupted keys, was that this also fixed the blank window when trying to view “Turn Windows features on or off” feature on our Windows 7 computer!

WARNING: Comp-U-Train will not be held liable  for any problems caused to your computer’s OS through the tampering of the registry!

We would like to say a big thank you to Raymond.cc for helping us connect the problem between the “Turn Windows features on or off” blank window and the Microsoft Windows update failure of KB2804579 issue.
