However, you need to edit the file in the ISO and do a clean install. You cannot delete it on an installed Windows.

Note:
I'm not sure if the way to edit "appxmanifest.xml" is correct.

Nice find!
I believe after install you can do the same in Registry, will investigate later.
 
I too would like to find a way to delete it even after it's been installed.
However, I have no idea how to search for it.
 
By the way,
the method for removing "Get Start" from "All Apps" is similar in the sense that it involves editing "appxmanifest.xml".
I have not yet found a way to remove "Get Start" from Windows after it has been installed.
So it looks like this problem will take some time to be solved as well.
 
You can hide several features by editing Client.CBS's AppxManifest.xml, before installation.

But this has two serious drawbacks:
- WU can no longer apply future Monthly CU's. Updating is always blocked at 25%, until you restore the original manifest.
- Applying the new CU wipes out your edits.

There are no problems with those issues.
In my case, I create a new build ISO every 1-2 weeks and do a clean install.
So I don't need to use "Windows Update".

Same for me, but every months (with new CU) :D
 
I was able to successfully apply the changes I made to "appxmanifest.xml" without reinstalling.

Steps
1. Boot from another OS. (Dual boot, LiveUSB, etc.)

2. Go to "X:\ProgramData\Microsoft\Windows\AppRepository\Packages\MicrosoftWindows.Client.Core_1000.26100.8.0_x64__cw5n1h2txyewy"
and take ownership of the 4 files in the folder.

3. Delete the 4 files.
ActivationStore.dat, ActivationStore.dat.LOG1, ActivationStore.dat.LOG2, machine.pckgdep

4. Reboot.

Note:
This method did not work for "All Apps", such as "Get Start".
 
Yes.
What I mean by that is that deleting the 4 files in
"C:\ProgramData\Microsoft\Windows\AppRepository\Packages\MicrosoftWindows.Client.CBS_1000.26100.6.0_x64__cw5n1h2txyewy"
after editing
"C:\Windows\SystemApps\MicrosoftWindows.Client.CBS_cw5n1h2txyewy\appxmanifest.xml" in a similar way will have no effect.
