Windows : Feature update to Windows 10, version 1803 – Error 0x8007007e

By | January 8, 2019

I have encountered the following error while attempting to install the latest Windows Updates (on Windows 10).

Feature update to Windows 10, version 1803 – Error 0x8007007e

The update was blocking at “Status: Installing – 49%” and then failing.

It appeared that since this PC have not been updated for a while, the update version 1803 was conflicting with the newer update 1809.

To resolve this issue, simply follow these steps :

1. Download the “Show or hile updates (WUShowHide)” utility from Microsoft (http://download.microsoft.com/download/f/2/2/f22d5fdb-59cd-4275-8c95-1be17bf70b21/wushowhide.diagcab)

2. Run “wushowhide.diagcab”, click on “Hide updates” and check everything except the updates that is blocking (in that case Windows 10, version 1803 need to be unhided)

3. Run the disk space cleaner from “This PC” on the C drive and click “Cleanup system files” at the lower left corner (check everything and click OK).

4. Reboot your computer and try running Windows Updates again.

The issue should be resolved at this point. Make sure to run “wushowhide.diagcab” again after to unhide the other updates – then run Windows Updates again to install the remaining ones.
