Windows 10 PPTP VPN No Internet

I know what you're thinking, "Just go to the VPN connection, right click and go to properties > Networking > IPv4 > Properties > Advanced > Uncheck 'Use default gateway on remote network'"

Unfortunately I cant do this, when I click on IPv4 and click Properties...nothing happens.

Does anyone know why its not letting me go into the properties of the IPv4 protocol?

I've tried restarting the computer. Deleting and readding the connection. No matter what I cant go into the properties. Although I can go into properties for my regular LAN connection.

If this is a windows bug, does anyone know a way around this? Perhaps a registry setting?

Thanks!

If you need to keep your Internet connection when you connect to the VPN, you can do the following:

Open "PowerShell" as an administrator, and with the following command you can fix it. Note that you should reboot the PC after this.

PS C: \> Set-VpnConnection -Name "YOURVPN" -SplitTunneling $True -PassThru

Israel's answer put me in the right track but I still has a few issues. Here is what I did to make it work:

Open "PowerShell" as an administrator and type:

Set-VpnConnection -Name "Your VPN Name" -SplitTunneling $True 

On the "Network and Internet" settings window, click on "Change adapter options", then right click on the VPN connection => Properties => Networking => Internet Protocol version 4 => Properties => Advanced => make sure "Use default gateway" is un-ticked.

At this stage I could connect to VPN and use internet... but only for a few minutes. After that Outlook got disconnected, and I couldn't access new web pages (old one that I had opened before connecting to VPN still worked). I realised something was wrong with DNS.

What I had to do was to go back to the Internet Protocol version 4 properties (c.f. above) and select "Use the following DNS server addresses" and type 8.8.8.8 in the "Preferred DNS server" box. This IP is Google's public DNS server. Feel free to use any one you prefer.

After reconnecting to the VPN is all worked normally (what a massive pain it was).
