There is a kind of hidden feature in the Windows 10 which lets you video capture the screen by just a few clicks. To record screen on windows 10, do as follows:
1. Open the app/program or the window/view you want to record the screen (video capture)
2. Press the Windows Key and G both at the same time to open the Game DVR menu. (You are aksed whether you want to open the Game Bar or not?)
3. You may need to mark the "This is a game" checkbox
4. A toolbox will open on the screen and all you have to do to record screen on Windows 10 is pressing the Record button
Note that, using this method you may face some limitations, including not supporting high resolution video recording. You can always head to the Store and look for screen video recording apps on Windows 10.
Tip: If you are looking for a fast shortcut to video record the screen on Windows 10, press Windows Key + Alt Key + R at the same time.
