Hello my name is ***** ***** certified computer professional with over 10 years experience. I will be happy to help you.
When you click start and choose all apps are you not seeing your programs you previously had? I am not sure what you mean when you say you have "no windows" so please explain that a bit further if you can.
Are you able to get to the windows 10 desktop, do you see a little windows flag on the bottom left?
