Windows 10 offers a new built in feature called Game DVR which will allow the user to record video of ANY open windows application or software (excluding File Explorer/ Desktop). To activate this feature, simply press the Windows Key + G on an open window. A dialog box will then open asking if this is a game. Check the box yes and now you should see a bar with several different options including the Xbox icon.
To start any recording, simply click the red record button or Win + Alt + G. To stop the recording, press Win + Alt + R. You have now created a video which can be found under Libraries > Videos > Captures. There are many different settings you can enable/disable in Game DVR such as Microphone use and Hot Keys. Theare are all accessible through the Settings Menu on the recording bar indicated by the Gear Icon.
