A combination of terrible antivirus software combined with really dumb ideas on the internet created a situation where a whole bunch of folks were disabling antivirus and other security features, which was leading to huge security issues across billions of devices. That, and malicious software figured out how to disable security measures as well, so Microsoft went nuclear and they do everything possible to reset things to defaults.

Of course, other teams saw this and Microsoft sometimes resets settings to things it unrelated to security, which just pisses everyone off.

Overall, they are doing a horrible job. They actually pushed me back onto Linux (likely for good, since all my software now works without compromises), and I've seen quite an uptick of folks who've done the same. Valve has made this easier by all their hard work getting games to "just work".

I'm under no illusion that Linux will gain significant market share overnight, however, things are shifting.
