How to stop using the “Run Unattended” mode

I have installed Tailscale in the “Run Unattended” mode. I now want to go back to the normal mode of operation, but I can’t figure out how to do that.

What I have done so far is uninstalled Tailscale and remove all references to it in the registry and the %AppData% folder and then rebooted.

When I re-install Tailscale again it goes straight back into “Run Unattended” mode.

How can I stop it doing this?
