A:AnswerThe only difference between Windows 10 and Windows 10 S is that the latter is meant to be restricted to run applications available on the Microsoft (S)tore. If this is too limiting for you, you can switch to the full version by going to the Microsoft Store. Directions can be found there, or Googled. Be aware, however, that once you go through this process, you cannot then return to S Mode, unless you were to install the OS from scratch.
