Original GitHub issue: https://github.com/netbirdio/netbird/issues/4927

Describe the problem

I work with multiple OpenVPN profiles, for that I usually create a bunch of TUN interfaces in Windows 11 with the following command.
.\tapctl.exe create --name "OpenVPN Test" --hwid wintun –persist-tun

These interfaces persist normally, including after reboot, as long as NetBird is not started.

However, after a reboot, when I start NetBird for the first time, all previously created persistent TUN interfaces are automatically removed. This does not happen if NetBird is connected and disconnected within the same session—they remain intact.

The issue is that NetBird appears to delete existing persistent TUN interfaces when it starts after a system reboot.

I'm having the same situation here. Netbird, please STOP doing this. This happens regularly and combined with the auto update system it breaks my network interfaces.
