You got the important details of the Microsoft parent wrong (the patent doesn’t use camera and microphone monitoring), but more importantly the existence of a patent is not the same as intent to deploy a technique.
Every few years news outlets will generate controversy about a patent they’ve discovered, implying that the company is going to force the evil thing on everyone. If you’ve worked at a tech company with a patent incentive you realize most of these patents are just resume padding junk or people gaming patent incentive systems. I was at a company that had a modest bonus for submitting ideas that could be patented and you wouldn’t believe the junk that people were trying to push through without any intent to ever use it.
As further proof, the patent you’re thinking of where cameras monitor the user is actually from 2009 and was patented by Sony. US8246454B2
