OT:
Muting your mic reportedly doesn’t stop big tech from recording your audio https://thenextweb.com/news/muting-your-mic-doesnt-stop-big-tech-recording-your-audioWhy am I not surprised. I long suspected that video conferencing software would have this issue, especially with all the world's WFH employees now on Zoom or similar.
It's a feature, not a bug. Big brother is listening, and your company is likely spying on your muted utterances.

Wanna mute and call your boss an fkn asshole, or that flake co-worker a bitch, under your breath? Better think again.

Good info. Muting audio is easy enough, muting the mic from the OS more difficult. I wonder if there's an easier way than suggested in the article.

It's also got a disabled Intel Management engine.
There' a serious bug in it that puts 100s of different computer models at risk.

Without a doubt.
