Windows Apps and disabling them using CMD Prompt in Windows Firewall..?

Hi all,

Noticed that the UWP Apps (those found in C:\Program Files\WindowsApps) do not respond to being disabled via the CMD Prompt by using:

'netsh AdvFirewall Firewall Set Rule name="WindowsApp Name" New Enable=no'

I can change the setting of these WindowsApps if I use 'group="WindowsApp Name"' instead of 'Name="WindowsApp Name" ' but that doesn'tlet me configure the rule beyond Enabling or Disabling it.

After dumping all the firewall rules to a text file using 'Netsh AdvFirewall Firewall Show Rule Name=all >C:\FW_Rules.txt' I noticed that the specific WindowsApps that don't respond to CMD Prompt Firewall Config Commands all have wierd names...

For Example:

@{Microsoft.Microsoft3DViewer_5.1902.20012.0_x64__8wekyb3d8bbwe?ms-resource://Microsoft.Microsoft3DViewer/Common.View.UWP/Resources/StoreAppName}
For a rule whose name appears in the Firewall UI as simply '3D Viewer'

So, in a nutshell:

Netsh AdvFirewall Firewall Set Rule Name="3D Viewer" New Dir=In Action=Allow Enable=Yes
Returns the error 'No Rules Match the Specified Criteria'

BUT

Netsh AdvFirewall Firewall Set Rule Group="3D Viewer" New Enable=Yes
Works fine.

LASTLY

In the .txt file generated by dumping the rules to a text file, the above '3D Viewer' application has the strange name:

@{Microsoft.Microsoft3DViewer_5.1902.20012.0_x64__8wekyb3d8bbwe?ms-resource://Microsoft.Microsoft3DViewer/Common.View.UWP/Resources/StoreAppName}

What is causing this and how do I make it so I can configure WindowsApps automatically using CMD Prompt?

This only seems to be the case in Windows 10 Version 1909.

Much Appreciated.
