I was just in the process of dual-booting Windows 11 and Linux Mint (on separate SSDs) and just resurfaced from a dive into this very topic. How serendipitous!
I won’t touch on any piracy aspect here ofc, but I will comment (in agreement with the topic title): Ideologically, with how ridiculous Microsoft is, they should be paying YOU for putting up with them. Well, at least sailing’s never been easier.
Anyways, back on Windows 10 I was using Patch My PC (Home Updater) to keep applications regularly, and conveniently, up-to-date. And while it still seems to be an option, for the time being I’m using:
Very smooth install / ease-of-use, uninstall, bulk updates, tweaks, “debloat” and more. Here’s a video:
In terms of more privacy / “debloat” resources, I’m familiar with the following:
- Windows Privacy Dashboard
- privacy.sexy
And, well, Github has some more:
windows-11-debloat · GitHub Topics · GitHub
It’s important to be mindful however of how randomly firing off all these scripts / programs, particularly in “wild-abandon” combination, could lead you to serious troubleshooting immediately or down-the-road, where you could just end up restarting from zero 
Finally,I was really pleased to learn that Rufus (“boot USB” creator) lets you optionally setup the install with a Local Account! What a concept! 
But anyways, the real solution to this problem is to install Linux btw. jk / not jk.
Hope this helps, homies!
