Windows 10 or 11

I have a computer with W10 LTSC running. It's a work site license but since installing it years ago, they've gone fairly aggressive with administrative access. I'm assuming it's from the license that they got access. I need to ditch their access. I'm assuming the only way is a full clean install.

For the sake of privacy going forward is W11 better or should I try to find a copy of W10?

I'm open to any suggestions.

Oh! Edit added... …
