Group Policy Editor to disable as much telemetry as possible

Hello everyone

I'm currently on a quest to disable as much telemetry as possible.

1) In the past, I was using utilities such as O&O Shutup10++ or W10Privacy. However, I'm not entirely satisfied for them.

• These tools are convenient but not open source. I trust them but it's not ideal.
• It's really hard to track what they're actually doing.
• They're not updated very often, which leads to my following grief.
• Lots of settings are outdated, and simply don't work. Since most of the time, it involves regedits, I think it's quite a problem and it can impact stability.

2) The settings app doesn't include all relevant options. It's also a PITA to go through it everytime I do a clean install. Settings are sometimes reset when there are big Windows updates. This solution isn't satisfying at all for me.



3) So I figured it out the best way to deal with it was to use GPE (Group Policy Editor). I've already read many articles, threads, to find most relevant settings. Since I'm a new member, I can't post links, but you'll be able to find my list on Github, my username is tom4tot and my repository is pinned (Windows-11-Personal-Setup)

I have a few comments:

• First of all, feel free to use it for yourself, that's why I created a repository!
• What do you think of my approach? As you can read on my page, it's extremely easy to backup/restore group policies, and it seems to be a clean way to deal with telemetry and Windows Settings in general (that you want to keep permanent).
• If you've already done something similar, I'd appreciate if you could point out what policies I could have missed and that are obviously relevant.

Thanks for your time!
