To create a restore point on Windows 8:
Next step: Uninstall the non-working miniports
When doing this, make a note of the miniports that you are removing, you’ll need to know this later when reinstalling.
Removing the Problematic WAN Miniport Driver
So, to remove each non-working miniport, do the following:
Reinstall the miniports
You’ll need to do a few extra steps, as the miniport drivers aren’t meant to be installed by users and are not visible. To avoid editing .inf files (which in a lot of cases are protected and not easily editable), we’ll do it the long way.
Download devcon.exe and extract it on your C: drive root
Go to command prompt, go to the directory C:devconi386 for 32 bit and C:devconia64 for 64bit
For each miniport that you have previously uninstalled, execute the command outlined below. DO NOT run all of them or run the command twice, as that will create a second version of the existing miniport, which can cause problems again.
If running the command Reports driver install failure, don’t pay much attention to it, it usually does. The only problem is when it complains about the inf file missing, or a missing class (in which case you most likely made a typo in the last part of the command).
Just copy the command and past it into the command prompt hit enter.
devcon.exe install c:\Windows\inf\netavpna.inf MS_AgileVpnMiniport
devcon.exe install c:\Windows\inf\netrasa.inf MS_NdisWanIp
devcon.exe install c:\Windows\inf\netrasa.inf MS_NdisWanIpv6
devcon.exe install c:\Windows\inf\netrasa.inf MS_NdisWanBh
devcon.exe install c:\Windows\inf\netrasa.inf MS_L2tpMiniport
devcon.exe install c:\Windows\inf\netrasa.inf MS_PppoeMiniport
devcon.exe install c:\Windows\inf\netrasa.inf MS_PptpMiniport
devcon.exe install c:\Windows\inf\netsstpa.inf MS_SstpMiniport
Once done, reboot. Again

You might get this error also if you are already connected to Dedicated IP with your other device. So check that before going all the hasle..
I’m on Windows 10 and the only solution was simply run PureVPN as administrator. No more 720 error.
devcon.exe is no longer available as an individual file. You need to download 800MB of Windows Driver Package. Better to reset your network by going in Settings > Network & Internet > Status > Network Reset —–>> works only for Windows 10.
We are sorry for the inconvenience. If you have followed above steps correctly and still getting error 720 then it may means that your mini ports are corrupted and you will need to reinstall Windows.
Let us know if you have further questions!
I will check if this guide does the trick!
I have tried to reset and remove the miniports without success.
My computer is a Surface Pro 4 – Windows 10.0.14965.
Only OpenVPN works
Uninstall pureVPN, reset network (and shutdown, don’t restart), and reinstall pureVPN.
(Reset network: Settings > Network & Internet > Status > Network Reset)
