I'll be using Windows 8.1 for a while longer. There is one Windows 10 improvement that would be nice if it could be brought over to Windows 8.1: the improved Command Prompt. Is it possible to just copy over Windows 10 Windows/System32/cmd.exe into Windows 8.1 and use that instead of the Windows 8.1 Command Prompt? Would there be any potential problems in the future? If this works, could this be done with Windows 7 too? Searching for this in Google shows no results at all. It seems like nobody anywhere has ever tried it!
