Kakarot96: As i said, there are other reasons apart from those 2 you mentioned. Also, you are using the same arguments some people used to defend a developer that puts things like Red Shell on their software:
The only other problem you mentioned is older games, and older games that don't run on Win 10 almost always don't run on Win 7 either, so Win 7 won't help you there.
Kakarot96: Also, you are using the same arguments some people used to defend a developer that puts things like Red Shell on their software:
Incorrect analogy. Red Shell's problem was that it was tracking data that was completely irrelevant to actual game performance. In contrast, the anonymous data sent by Windows is useful for helping Microsoft actually work on Windows.
Kakarot96: "But i have nothing to hide so, what's the problem?"
In this case, that literally is the situation: You don't have anything to hide, so you don't have a problem.
Basically, the level of hoops needed to attach the anonymized data to your identity would be significant, so nobody is going to bother unless you've given someone an overwhelming need to know everything you specifically are doing. And if that's the case, then posting here on this forum is just as much of a risk to you.
Since the hard reality for better or worse is that privacy in the modern era is mostly an all or nothing deal. You either have to take steps to essentially retcon your entire existence and work in the shadows, or you do your best to avoid the stuff that would make it easy to moderately possible to hurt you and accept that most people are not important enough for someone to take the hard way to hurt you.
Especially in this situation where removing the tiny risk of loss of privacy opens you up to the much greater risk of security and malware snafus that will no longer be patched, so the tradeoff just isn't worth it. You'd be best off jumping ship to Linux if you truly don't want to run Win10.
And in the long run the better prep work if you're truly concerned is instead assuming that you will get got at some point and limiting how much damage getting got would cost you. Since doing this selective thing of railing at Windows yet still doing things like running gaming platform software and posting on a forum which share other types of data about you anyway, unfortunately doesn't accomplish anything except giving you false reassurance.
I don't think people realize just how much data we get sent about ourselves nowadays by basically everything. Correctly erasing yourself and keeping yourself retgone is practically a full time job where you accept the removal of large swaths of comfortable living because the consequences of the loss of privacy would be even worse. It's not something you can accomplish just by avoiding a handful of sites or programs and calling it a day.
