Supplementary information from the site:

Occasionally you may need play with different TAP-driver versions. In this case you can use devcon.exe from the Windows command-prompt. Below are some common commands you can run from an administrator Powershell
or cmd.exe console:

To verify TAP-driver removal:

Install a new TAP-driver:

Update a TAP-driver:

Notes:

• <id> refers to the driver identifier which is tap0901 for OpenVPN 2.2+, but may be different in older/newer OpenVPN versions.
• <something.inf> is typically OemWin2k.inf (old tap-drivers) or OemVista.inf (newer tap-drivers). You need to specify the full path to this file, e.g.C:\Program Files\TAP-Windows\driver\OemVista.inf.

By installing multiple times, you will create additional TAP-Windows adapter instances, which can be used for multiple concurrent VPN tunnels. It is also possible to install using Control Panel -> Add New Hardware,
and it is possible to uninstall using Control Panel -> System -> Hardware -> Device Manager.

 

OpenVPN "All TAP-Windows adapters on this system are currently in use." error

I have been trying to set up OpenVPN on Windows 10 home on my new laptop (64bit). However, I have encountered a problem. I can not connect to any of the VPN servers. When I checked the logs, right before the fatal error was "All TAP-Windows adapters on this system are currently in use.". I used .ovpn files provided by my VPN provider. I also am sure that I am using accurate credentials.

I have re-installed OpenVPN multiple times, making sure TAP adapters were removed and installed again. However, that did not change anything.

When I checked the list of Network connections from the control panel, I found that "TAP-Windows Adapter V9" was recognized as "Unidentified network". Disabling and enabling TAP Adapter from this screen disconnected the adapter from "Unidentified network", changing the status into "Network cable unplugged". In this state, I was able to connect to the VPN. However, if I did not connect to the VPN and wait, TAP adapter quickly went back to being "Unidentified network", preventing me from connecting to the VPN again.

Checking the "TAP-Windows Adapter V9" from the device manager to "Update driver" yielded nothing. Windows stated I already had the best driver.

How can I stop the TAP adapter from being recognized as "Unidentified network"?

Thanks in advance.
