I've been dual booting Windows and Linux since the 00s. At some point around 2015-2016 I just stopped installing and maintaining Windows altogether and now I have a virtual machine image I just transfer around my network if I ever have to use Windows for something.

I think the real turning point for me was when they introduced UAC and ever-increasing restrictions on unsigned drivers starting with Vista. Wine was already a thing and I could run most games I cared about even back then although I still had to boot into Windows for gaming sometimes. Once steam Proton starting getting really good which was around 2015, there just wasn't a reason to be using Windows anymore. As the enshittification of Windows continued getting worse it became more tedious and time consuming to get anything done in Windows to the point you might as well use Gentoo. I do programming and game modding for fun and there's no way I could use modern Windows for this it's so bad and slows everything down with it's utter bullshit.
