Windows 10 Pro N fails applying the April 2018 update

Solution 1:

If you navigate to the following folder: C:\$Windows.~BT\Sources\Panther you'll find a file called setuperror.log

If you open that file, the reason for why the error fails will be shown there.

If you have an N version of windows 10, it is quite likely that you will find the following line in this file:

Operation failed: Add [1] package 
C:$WINDOWS.BT\FODs\DU\f5d394a9-b4f4-457c-b5f8-438a6b8e72a0\
Microsoft-Windows-MediaPlayer-Package31bf3856ad364e35~amd64~~.cab. 
Error: 0x800F081E[gle=0x000000b7]

This will happen if you have installed the Media Feature Pack in the past to add back support for Windows Media Player and the H.264 codec pack for use with websites such as Youtube, SoundCloud, etc.

In order to succesfully upgrade your installation, you need to uninstall the Media Features.

Here's how:

1. Open Control Panel
2. Go to Programs and Features
3. On the left side, access Turn Windows Features on or off
4. On the new window, untick Media Features. It has a subfolder with Media Player, but you need to uninstall it completely.
5. After it is removed, you can run the upgrade again (using the Media Creation Tool) and it should work this time. No need to reboot after removing the feature unless a popup is shown asking you to reboot. (didn't happen to me, so I did not reboot, and it worked great.)

Don't forget, to install the new Windows Media Feature pack, which can be downloaded from here.

Solution 2:

I've had this issue on 2 machines running Windows 10 Pro N. The main thing to do is uninstalling media features AND Windows Media player.

After you do that you can just reinstall this specific 1803 update (even without the media creation tool)

Here's what to do:

1. In "Turn Windows Features On or Off" Expand Media features -> untick Windows Media Player -> Press OK

2. "Apps and Features" ->click "Manage optional features" -> Remove Windows Media Player

3. Check for updates and install

If all else fails use the Media creation tool

This is a major oversight and I suspect it affects all Windows 10 N with the Windows media player. Microsoft really need to resolve this ASAP. I spent hours until I managed to find this thread and fix it,
