Change Network connection from Public to Private powershell oneliner

Question

Im working on a Ducky Script winRM backdoor and to set winRM up, the User must be connected to a network on a Private connection. How can I automate this with powershell commands?

Get-NetConnectionProfile shows all the currently connected network. I would like to make a loop that filters that output and puts every network name in this command Set-NetConnectionProfile -Name "NetworkName" -NetworkCategory Private

Answer 1

The Question is answered easily with the following:

Get-NetConnectionProfile | Set-NetConnectionProfile -NetworkCategory Private

Answer 2

Get-NetConnectionProfile only retrieves active connections.

If you truly want to change all connection profiles to Private here's some code I wrote to accomplish that task.
