Here is how to create a shared VPN connection in Windows 10 that you can connect to at login. Super handy for pre-joining a domain to configure before taking a new computer onsite. Basically the same thing as the old “Allow other users to use this connection” from previous versions of Windows. But Windows 10 will let you connect the VPN and log in in one motion. Neat!

To create the shared connection, fire up powershell as admin and run this:

Add-VpnConnection -Name MY_VPN_NAME -ServerAddress MY_VPN_SERVER -AllUserConnection $true -SplitTunneling $true -AuthenticationMethod MSChapv2 -TunnelType Automatic -EncryptionLevel Required -PassThru

Then you can jump into the network connections (run ncpa.cpl) to edit as needed for your particular set up.

Got the code from this ServerFault post
