Where possible I always use local accounts on Windows, none of this signed in to MS bullshit.
Chances are MS is still tracking you via TPM and/or hw/peripherals.
I can’t not register Windows 11, because despite everything I try to erase my hardware footprint, it still ties it to my digital license.
This goes as far as upgrading every single piece of hardware on my PC, and using an entirely different ISP.
And no. I don’t use any Microsoft services on Win 11. I don’t use Internet in any capacity when installing. Nor do I use any cd keys for Windows.
Everything the installer asks me, I answer “No.” to.
This should honestly be a huge privacy concern but alas.
Win 11 license is tied to your motherboard. Switching anything besides that won’t change anything. Did you do a fresh install without Internet when you swapped your mobo? Besides that: you could go with Win 10 (preferably LTSC). Your only other option is to ditch Win for an OS that verifiably respects your privacy.
I upgraded everything except one NVMe.
Also read what I actually wrote. Full offline installs always.
And linux would be an option except Nvidia.
