Windows is not accesible even to people without disdabilities. I have to carefully select the background color or else i will end up with a light text colour on light background or dark text colour on dark background. Or to search half of hour for the cursor in a Word document because Microsoft decided that blinking the cursor is so 80s and the cursor is hidden.
Use an alternative Windows DE, I guess (are those still around?). Or just use Linux.
No OS is as flexible as Linux and it can't be, since desktop Linux frequently doesn't offer support so you can do whatever you want to it but it's on you to fix it.
