Well, apart from not being good, it would be impossible to do so as Win10 is full of bloat like all Windows versions. The original HD and RAM would not be sufficient, and neither would the GPU or processor IMHO. Of course, if the user upgraded all the hardware, RAM and processor for every release, then you might get away with it, but not all motherboards can be upgraded easily. To end this, Win10 will only work on a very modern PC, and considering the load of bloat they are adding on every upgrade recently, many budget PCs will die the Windows death. Suggest you all look to move away from the blue screen of death, and go the Linux route.....and yes, your games will work with an emulator, as does mine. I have been free of that bloat for nearly ten years and can still do all i wanted when i suffered that other OS.
Just do it guys, you know it makes sense!!
