Alternatively, consider the following:

• look around for a $50-100 used PC/mini-pc/laptop that someone is getting rid of because it won’t run Win11
• install something easy like Mint on it and use that for day-to-day stuff like browsing and office-type stuff.
• unplug the music PC from the internet and keep DAW, games & win10 on it
• explore and learn the Linux stuff in a low-pressure way, at your own pace.

to tell you the truth, I don’t know! I think I just saw someone asking about tiling window managers in some forum, and a reply suggested trying the xfce functions since they mostly just wanted to use two side-by-side windows occasionally. I do it a good chunk of the time now, but it’s not always the most convenient method on small screens & monitors

Even just the key combos (win+numpad) to do basic tiling in XFCE are a huge plus
