Step 1

From an elevated PowerShell window issue the following command to gather some information about our current network profile:

Get-NetConnectionProfile

Name             : Unidentified Network
InterfaceAlias   : Ethernet
InterfaceIndex   : 10
NetworkCategory  : Public
IPv4Connectivity : LocalNetwork
IPv6Connectivity : LocalNetwork

The only information we really need from this output is the “InterfaceIndex”

Step 2

After getting the InterfaceIndex, we run the following command:

Set-NetConnectionProfile -InterfaceIndex 10 -NetworkCategory Private

The last argument is what category you want to switch it to. The only allowed values here are “Public” or “Private” as per the MSDN documentation. The category can also be “DomainAuthenticated” but Windows will automatically assign this when the machine is added to a domain.
