Things were still overridable, but XP started the trend where the end user was not an allmighty sysadmin responsible for its own deeds good or wrong, but a consumer that should follow the vision of Microsoft and not touch the holy internals.
I can partially defend microsoft here. Everybody and their dog was messing around in the registry, was installing all kinds of system-breaking software, etc... But it also signifies a point where Microsoft realised it got powerfull enough to ignore the wishes of its own clients.
The analogy would hold if, dunno, buying some DRM Music also made you relinquish the ownership of your speakers to the vendor. It’s not quite as bad.
DRM is, for example, a way to kill the second hand market or lending. I can sell my table without approval from its manufacturer, or drag it to my neighbours for a day. I can't sell my songs.
In the same spirit, if I as a computer enthousiast want to upgrade my computer hardware or reinstall windows, I should not depend on microsoft's goodwill.
Windows Vista and onwards, MS, while claiming it was for technical and stability reasons, nixed a lot of features that were annoying to movie studios, basically they changed how driver stack worked in a way to make DRM easier and make harder to pirate movies.
But as consequence of that, a lot of cool stuff outright stopped working:
* Some interesting video modes
* Some obscure ways to output data
* And the one that annoyed me the most: Soundcards became useless.
Before that, Soundcards could do a LOT, they could have their own processor and do a lot of fancy stuff, most famously they could do "3D Audio", and it was super cool, Thief for example is a game that uses it well, it would use its own processor to do same thing GPUs do for graphics, and do it for audio, it would even raytrace sound (ie: suppose a character is on the other side of the wall, but there is a door on that wall, the card would calculate the sound of that character footsteps reflecting on the walls and reach you, then if you were using headphone or 4+ speakers it would make you hear the sound coming from the reflections, thus a person with good hearing could deduce where an enemy was, on the other side of a wall).
That stunt basically killed off the soundcard market, people then were making cooler and cooler cards, after that the cards became little more than just output ports soldered on a tiny board.

I'll just add—forced upgrades to Win10. Still hard to believe how much (some divisions of) MS despises its own customers. I call them the "Balmer camp" as a shorthand.
Despite parts of MS turning over a new leaf, the sociopath wing persist.
