You mean like Skype for Business?

Platforms like Windows and Chrome can also use it for remote attestation, i.e., verifying you haven’t bypassed security controls and locking you out if they think you have.

I keep mine enabled because it’s good for secure boot and secrets handling.

You hold down Shift while restarting or booting and you get a recovery menu. I don’t know why they changed this behaviour.
