Most people cannot install or debug windows. For most people the biggest issue is their support network. My father-in-law and my wife run Linux and have done so for 20 years. They are not technical and it works just fine. My mom uses Windows and I have not suggested Linux because I am not local. She needs a local support network. I spend as much time or more supporting her.
The worst barrier is explicit hardware compatibility not software. Most hardware works but you never know. For software most things have FOSS eqyivalents. If you actually want to run commercial software then sure Windows or whatever platform it runs on.
