How to fix error code 0x8007007e?

First of all, you should perform the Windows Update Troubleshooter. You will need to download and run the version of Troubleshooter compatible with your computer, which you can find here. You should then perform a clean boot in Windows, for which you can find instructions here.

A Microsoft moderator on their forums also recommend temporarily disabling 3rd party anti-virus programs. If you have one installed, try disabling it until you complete the updates. Another recommended method is to reset Windows Update components:

  1. Press Windowskey and X at the same time. Press on Command Prompt (Admin).
  2. Type the following and press Enter after each command:
    • net stop wuauserv
    • net stop cryptSvc
    • net stop bits
    • net stop msiserver
    • ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
    • ren C:\Windows\System32\catroot2 Catroot2.old
    • net start wuauserv and press Enter
    • net start cryptSvc
    • net start bits
    • net start msiserver
  3. Close the Command Prompt (Admin) window.
  4. Try to perform the upgrade again.

Another method proposed by one user in a forum is to replace the C:\Windows10Upgrade\wimgapi.dll with the one from C:\Windows\System32\wimgapi.dll.

If none of these methods to fix error code 0x8007007e worked, try to manually update/upgrade. You can download updates for manual installation here.
