How to setup a kill switch on Windows 7 and 10

1. Check and change the windows network profile of your local area network

Windows 7

- Click on "Public Network" underneath the network
Windows 7 Network And Sharing Center Network

Windows 7 Set Network Profile

Windows 10

Click on Private
Windows 10 Network Profile

Open up Advanced Firewall settings.  You can search for this in the start menu
3. Backup your current firewall settings.  Click on Action > Export Policies.  Pick a location and save the file
4. Action > Restore Default Policy > Yes
Windows Firewall Restore Default

Click on Windows Defender/Firewall Properties
 Windows Firewall Advanced Settings

4. Under Domain Profile, set Inbound and Outbound to Block (like below)
Windows Firewall Domain Profile

5. Click on the Private tab, and set Inbound and Outbound to Block (like below)
Windows Firewall Private Profile Settings

6. Click on Outbound rules > New Rule > Program > Next
Windows Firewall New Rule

7. Click on browse then browse over to the following path C:\Program Files (x86)\OpenVPN Technologies\OpenVPN Client\core and select capiws.exe
Windows Firewall rule OpenVPN

Click Allow the connection > Next

Windows firewall rule openvpn allow

10. Uncheck Domain and Private > Next
windows firewall openvpn rule profile

11. Give the rule a name then Finish
windows firewall rule openvpn name

12. Click on Outbound rules > New Rule > Port
windows firewall rule port

Select UDP and enter in 53
windows firewall dns 53 rule

14. Select All profiles > Next
windows firewall rule 53 rule allow all
15. Give the rule a name > Finish
16. Repeat steps 12 - 14 the for UDP port 1194 and TCP port 443.  Both these ports are required for the connection to be successful

If you ever get a firewall popup to add a program, make sure to uncheck "Private networks" and only have "Public networks" checked before clicking Allow access; If you fail to monitor this, the killswitch will be pointless
