I really enjoy Linux but I find myself having to keep Windows partitions around for software that specifically requires Windows.
Proton makes everything easier by automatically running game files through a translation layer, and it “just works” quite well most of the time.
Also VanillaOS can apparently auto-spin a container when you try to open a .deb or AUR package (this is my rudimentary understanding).
Setting up WINE/Bottles, etc. is above my pay grade.
Is it not possible to create an OS that just does the same thing as Steam but for the entire OS?
Try Zorin OS

Can confirm Zorin has the best out-of-the-box process for getting Windows apps running. I have a family member that’s really gotten attached to Zorin because of its familiar front-end, and even though they have some prior Linux experience from earlier years, they’ve never needed to use terminal knowledge for the basic stuff they’ve been using Zorin for.
Zorin is the answer for someone who needs easy mode to install .exe’s.
