It does not enable itself; it is enabled by MS when they change the status of those experimental features.
Some are made permanent and cannot even be disabled. Welcome to the A/B testing B.S. 🤣🤣🤣😜
All it takes is to go online and check for updates and after next reboot those features settings are changed.
That ain't right.
They can A/B test all they want but they shouldn't mess with user settings once the feature has been enabled.
Well, they do. I complained more than once, but they don't seem to listen. 😜😜🤷♂️
I have machines with the same build level, and they all behave differently because they play with those hidden features settings.
