SysPrep Windows 10 Pro Error (0x0f0070 & 0x0f00d8)

So I managed to fix this by tinkering a bit with the Appx .NET package. I had a second user that was created during setup on VMware. "Admin" and "Administrator" were on the system. So I logged into "Admin" and ran:

Remove-AppxPackage "Microsoft.NET.Native.Runtime.1.0_1.0.22929.0_x86__8wekyb3d8bbwe"

I was then confronted with an error stating that "Microsoft.Skype" is using this .NET Runtime and removing the .NET package was not possible.

I had to quickly search for the correct package that this error was referring to by issuing the Powershell command:

Get-AppxPackage -AllUsers | Select-String "Microsoft.Skype"

It then showed a single Microsoft.Skype Appx Package!

I then removed the "Microsoft.Skype" Appx Package and proceeded to run the above command, it worked!

My next step was to do the same on "Administrator". So I did the above and ran Sysprep again, boom! It works. Hopefully this helps someone in the future. :)

TL;DR:

1. Attempt to remove Appx package on any other user except the built-in Administrator, this should throw an error/conflict with another App;
2. Search for the App using the above Get-AppxPackage -AllUsers command
3. Remove the conflicting application to the be able to remove the primary issue-raising application;
4. Do this for all users, including the built-in Administrator; and
5. Sysprep should work again.
