I used to have a Windows 7 system and a Ubuntu system. One day the Windows system broke down, and I switched to using the Ubuntu system for almost everything. Over time, that became "everything". I haven't turned on the Windows system in months.
I recommend go to local policy and enable full audit for everything. When this happens in the future you'll have a clear picture of who/when/what.
And all the time, I have to fight the Microsoft way of doing things ... Worse the Apple, Microsoft push really hard to force me to do things their way. Eg. initially and after upgrade, it defaults to save everything on the MS cloud - NO, I have a perfectly good cloud of my own and don't want to pay MS extra.
I completely stopped using windows in the 8.1 days (forced telemetry was the last straw). I can't imagine dealing with the sorts of gaslighting you are experiencing.
Happily, a combination of steam proton and dosbox run dos / windows games on my Linux desktop more smoothly than native ever did, and that was my last missing use case.
