If you find that you are no longer able to connect your VPN following the Windows 10 'creator' update. please try the following:


1) You may need to repeat the registry change to allow the VPN through the firewall. Please floor these instruction:


A one-time registry change is required if the VPN server and/or client is behind NAT (e.g. home router). You must reboot your computer when done. It is good practice to backup the registry first.

For Windows Vista, 7, 8 and 10

Open a command prompt (CMD) as administrator , and copy and paste the red text below. Then re-boot your machine.

REG ADD HKLM\SYSTEM\CurrentControlSet\Services\PolicyAgent /v AssumeUDPEncapsulationContextOnSendRule /t REG_DWORD /d 0x2 /f

2) If you are still having issues after this, and you are using OpenVPN, check in 'Services' and ensure that all OpenVPN Services are set to automatic. If they are set to 'manual', change them to automatic, and then reboot your machine.
