Set a default associations configuration

Hi Guys,

I'm deploying Windows 10 Enterpise November Update (Build 10586) via MDT. I have set VLC to be the default audio/video player, Adobe Reader to be the default PDF viewer and Chrome to be the default browser.
I used this tutorial to create an xml file of the settings using Dism /Online /Export-DefaultAppAssociations.
After setting the default associations configuration file in Group Policy, VLC and Adobe Reader are succesfully the default programs but Edge remains the default browser. It should be Google Chrome.

Because it is not working I tried the registry tweaks that I found on this website:

<?xml version="1.0" encoding="UTF-8"?>
<DefaultAssociations>
  <Association Identifier=".htm" ProgId="ChromeHTML" ApplicationName="Google Chrome" />
  <Association Identifier=".html" ProgId="ChromeHTML" ApplicationName="Google Chrome" />
  <Association Identifier="http" ProgId="ChromeHTML" ApplicationName="Google Chrome" />
  <Association Identifier="https" ProgId="ChromeHTML" ApplicationName="Google Chrome" />
</DefaultAssociations>

But this results in Edge saying "An app default was reset" (to Edge). To fix that I tried the fix
on this website to no avail. I have downloaded and installed the windows 10 1115 admx templates and the Google Chrome admx templates and I have set Chrome to be the default browser in user settings.
This is not changing anything. (I know the user has to start Chrome once for this to take effect).
The weird thing is that settings the default associations through the xml file as well as setting Chrome as default browser works at 5 other locations but this location... not so much.

What could be the culprit?
