This question is basically the same as one I posted 2.5 years ago here, except that now I am using a different laptop that runs Windows 10 instead of Windows 8.
My laptop has a camera. Since it can obviously take video of me (a la Skyping), it should be easy to create a video of myself practicing a presentation.
My laptop runs Windows 10.
This is going to be a long video -- 1.5 hours. What is the easiest way to accomplish that using apps that come with Windows or something free that I can download?
