Try Snagit or Camtasia. Alternatively Windows 10 has a built-in screen capture tool. Heres how:
Locate and run the Xbox app
With the Xbox app running, jump to the app you want to record and press the 'Windows' key with the letter 'G' (Win + G) to open the Game Bar.
Tell the Xbox recording app that you want to open the Game Bar by telling it you want to record a game.
Once the Game Bar is loaded choose your action, either Screenshot (for a single image capture) or Start Recording (for capturing video).
