Couldn't you also make a throwaway ms account?
I could, but them I'm up a creek later if I need to use any recovery functionality, as it all ties back to that MS cloud account.
It's certainly possible to get working, disable all of the cloud saves and telemetry, and then just save the MS account in a password vault for later.
But all of that is much more work than clicking "next" a few times in the Linux Mint installer. ¯_(ツ)_/¯
After a few aborted attempts to switch to Linux, over the years, that has been exactly the vibe of my latest journey.
"So this all just works now?" has been my repeated surprised thought.
Standard disclaimer: I don't have any hardware by Nvidia. Not by choice, I was just feeling broke when Nvidia got hot.
