For Enterprise/Education you can disable the ‘recommended’ section entirely via group policy. Doesn’t work for Pro/Home versions though, from what I remember.
That would be odd. Usually Pro supports all the same group policy settings, and group policy settings usually just mess with registry keys that also work on Home edition.
It’s not 100%, but I’ve not run into any significant differences between Enterprise and Pro yet (besides the ability to centrally manage group policy etc).
Edit: On 10 Pro you can disable it entirely via Group Policy. It’s how I have mine configured.
For all types you can easily manage it in the GUI too.
Settings > Personalization > Start and turn off the toggle for “Show recommendations for tips, app promotions, and more.”
