It should be well known by now that if you're running Windows 10, Microsoft is your system administrator, and can control (at least technically) exactly what runs on your computer. Unless maybe if you really put time/effort into stopping that (if it's still possible at all).

This is not meant to be judgemental. I'm actually of the opinion this is better in general than leaving sysadmin duties to the general public, which was largely the situation in the 1990s / early 2000s. But outsourcing this to Microsoft does of course have it's downsides, like you just experienced.
