The best resolution for the TAP-Windows Adapter V9 error might be to reinstall the driver altogether.

However, considering that most TAP adapter drivers are a dependency for VPN clients, most VPN providers come with their own version.

Thus, it would be easier to just uninstall the TAP driver and your VPN client, and perform a clean install of both services after you’re done.

This is how you should reinstall your TAP driver and VPN client:

1. Right-click the Start button
2. Select Device Manager
3. Expand the Network adapters category
4. Right-click the TAP-Windows Adapter V9
5. Click on Uninstall device
6. Select Uninstall to confirm
7. Press the Windows key + R key combination
8. Type appwiz.cpl and press Enter
9. Select your VPN software in the window
10. Press the Uninstall button to remove it
11. Proceed with the uninstallation
12. Restart your PC shortly after uninstalling both services
13. Reinstall your VPN software + TAP adapter driver

If you notice that reinstalling your VPN client and TAP adapter driver didn’t work, you might consider switching to a better alternative.

Private Internet Access, for instance, is an excellent VPN service that comes with its own TAP driver.

Furthermore, even if it stops working at some point, you can easily reinstall it directly from the VPN client’s configuration screen.
