Full removal requires a Safe Mode reboot, a registry step, and then a standard Control Panel uninstall in that order.
Start the computer in Safe Mode see the OS-specific steps below.
Open File Explorer and go to C:\Program Files\Spriv LLC\Spriv Credential Provider\.
Double-click UnregisterFilter.reg to remove Spriv MFA for RDP from the registry.
Restart the computer. The Spriv login screen will still appear.
On the left side of the login screen, choose your original login method and log in.
Once logged in: Control Panel → "Uninstall a Program" → select "Spriv Credential Provider for Windows" → click "Uninstall."
After the final restart, only your original login method will be available.
Start → Power icon → hold Shift and click Restart → Troubleshoot → Advanced Options → Startup Settings → Restart → press 4 to enable Safe Mode.
Turn on or restart the computer, hold F8 before the Windows logo appears, release when the menu shows, use arrow keys to highlight "Safe Mode," press Enter.
