TAP adapter not appearing

Hi there,
Having deployed and installed VPN on many laptops before, now I've found an issue that I'm not able to solve...
TAP adapter does not appear on network adapters.
It is correctly installed. I've even manually added it (running "Add TAP..." as administrator). I get no errors but adapter does not appear and VPN does not work (error: All TAP-Windows adapters on this system are currently in use).
Laptop is completly new. Unboxed two hours ago. Windows 10 Home. Running as administrator.
However, it has no physical ethernet adapter (only wifi) and I think this could be the reason of tap adapter not adding/showing/working...
Also tried to uninstall and reinstall OpenVPN...same problem.
Any ideas?
Many thanks!

Wifi or ethernet makes no difference.
What does
ipconfig /all display ?

Wi-Fi Direct Virtual Adapter
Wi-Fi Direct Virtual Adapter #2
Realtek RTL8822CE 802.11ac PCIe Adapter

No TAP adapters...

First, what is the laptop ? And second, have you run Windows Update ?

Laptop is HP 15s-fq1044ns
Windows was completely updated to latest version/drivers just after unboxing it. Next step was installing OpenVPN. No other software has been installed on it. It is a completely clean system.

How about
Code: Select all
C:\Program Files\Openvpn\bin\tapctl list

File does not exist.

No TAP on device manager. Nothing with errors/warnings.
So...
I had no time and I did a system restore (factory reset) to the laptop.
Installed OpenVPN just after system restore and now works fine.
Thanks for your help anyway.

It seems I have the same problem on my Win 10 home and latest OpenVPN client 3.5.0. I have my VPN server and all worked well for a month, suddenly on PC it refuses to work(connects to the server with no error, but no internet), I believe the problem is with adapter, as I don't have TAP adapter anywhere.
But instead I have according ipconfig
Code: Select all
"Unknown adapter OpenVPN Connect DCO Adapter:
Media State . . . . . . . . . . . : Media disconnected
Connection-specific DNS Suffix . :"
Not sure if its made by intention, but OpenVPN uses this instead, managed to track it by Wireshark
Code: Select all
Unknown adapter Local Area Connection:
Media State . . . . . . . . . . . : Media disconnected
Connection-specific DNS Suffix . :
I had Avast antivirus running, after its removal and reinstallation of OpenVPN it worked well till restart. Now it's all same, I've tried to disable built-in antivirus and firewall but no luck so far. The server seems to be good, I still able to use it on my phone/tv within same network as my PC.
If you have any thoughts what could be the problem would be great to hear.
Thanks in advice.
