Nvidia Shawdowplay. https://www.nvidia.com/en-us/geforce/geforce-experience/shadowplay/ I find it easy and also has a keybind to grab the last 5 minutes in the event you were not recording and did something you wanted to grab.

Q. How do I use the Game Bar in Windows 10?
A. Windows 10 includes a new game bar that makes it easy to record clips of games and screenshots. The bar is opened by pressing the Win + G combination and when starting an application that Windows 10 knows is a game will remind you that the game bar can be used as shown.
Once you press Win + G the game bar is displayed that enables you to perform various actions such as screen shot, screen record. There are also settings to auto record and make a certain amount of time always available (for when you do something cool to make sure its captured).https://www.youtube.com/watch?v=sbdWpUmoQjU
