Hello Rick. After a Windows 11 update, it is common for the ExpressVPN TAP network adapter to disappear due to driver signature enforcement or compatibility resets. To fix this, first open Device Manager, expand Network adapters, and check if the ExpressVPN TAP Adapter is listed. If it’s missing, reinstall ExpressVPN to restore the adapter.
If you see a Code 52 error (driver signature issue), you will need to temporarily disable driver signature enforcement using:
bcdedit /set testsigning on
Run this in Command Prompt as administrator, restart your PC, reinstall ExpressVPN, then re-enable signature enforcement with:
bcdedit /set testsigning off
This process restores the TAP adapter and resolves connection issues caused by the update.
Here's the reference: Unable to connect: All TAP-Windows/TAP-Win32 adapters in use
