He uses Windows for almost anything. The things he does use that are not Windows based are very few and he doesn’t usually explain in detail what they are… because he doesn’t know what they are.
He is a Windows fanboy. He praises how some things are so simple to achieve in Windows (no doubt there, some things are), but lacks to mention how complicated others are… like let’s say get rid or old updates… which used to be a real problem until a few years ago (I now understand that it is again a problem in Windows 11).
Using an OS suited to his needs (gaming/content creation) isn’t being a fanboy, it’s using the best possible tools for the job. Linux is still a worse gaming experience than windows, no matter what way you try to sell it
