Fix Error code 0x8007007E on Windows 11/10
Let us look at the potential fixes for the three different scenarios.
Fix Windows Update error 0x8007007E
Windows 11/10 Update Error Code 0x8007007E occurs when the updates are not in sync. This happens for both Windows 11/10 standalone computers, and when you are connected to the Enterprise. Windows Server manages updates across all the computers in the Enterprise network.
Microsoft points out that when a hotfix is not installed before synchronization, this happens.
Occurs when update synchronization fails because you do not have hotfix installed before you enable update synchronization. Specifically, the CopyToCache operation fails on clients that have already downloaded the upgrade. Its because the Windows Server Update Services has bad metadata related to the upgrade.
To fix this, we need to repair the Windows Server Update Services. For the enterprise, if you have multiple WSUS servers, you need to repeat the same on each server. You can also choose to run it only on those servers that synced metadata before you installed the hotfix. IT Pro can check the WSUS log using the WSUS admin console or the API. This can help them figure out if the metadata sync status.
1] Delete contents of software distribution folder manually
Windows download all the update files into this folder. It acts as a buffer before installing it on the Windows 10 computer. Make sure to delete contents of the software distribution folder (C:\Windows\SoftwareDistribution\DataStore) manually. You will have to stop the Windows Update Services before deleting those files. Once done, restart the Windows Update service.
This applies to both standalone computers and Enterprise computers.
2] Run Windows Update Troubleshooter
If you have a standalone computer, you can run the troubleshooter. Windows comes with an inbuilt Windows Update Troubleshooter. You can run that which will resolve the problem around Windows 11/10 Update to fix this issue.
Once the computer is in sync with the Update server (Microsoft Update Server or Enterprise Server), all necessary updates will be installed first. The rest of the updates will follow up next.
Fix Error 0x8007007E in Outlook
When this error shows up in the Microsoft Outlook client, it inhibits the user from sending or receiving any emails. This usually happens for two reasons –  where the end-user is trying to upgrade to Windows 11/10 and  if the user upgrades to the next version of Office. There are two ways to fix this issue:
1] Repair/Reinstall Office Outlook Client
If repairing Microsoft Outlook does not help, you could install the mail client again. Sometimes an upgrade messes up the configuration when the version changes and reinstallation will fix it.
2] Run Outlook as administrator
Search for Outlook in the program menu, and then Shift+right click and select Run as administrator.
Fix Error 0x8007007E in Printer
This error shows up when a client machine tries to connect with a Remote Printer. You will see an error message which will say “The specified module could not be found”. Also, this happens in a server-client environment.
When the 32-bit universal driver is installed on the server, it creates a registry entry. This key tells the client machine that it needs a copy of a DLL file for the printer to work on the client machine.
However, if it’s a 64-bit client, it will need a 64-bit version of the driver. But since the server offers a 32-bit version driver(because of the registry entry), it results in this error. The registry entry on the server is located at:
To resolve the issue, just delete this key. Post this, when a request is made by a 64-bit client, it will no longer be told that they need to copy the wrong file.
