Microsoft now offers a possibility to create screen recording with Microsoft PowerPoint 2016. The recorded Screen can be saved as MP4 File, so that you can create a video for your users.
- Record a selected area from your screen
- Trim your video
- Save your video as MP4
- Use default PowerPoint Styles
- Use a pointer and/ or audio

Details about the functions and how to use this option in PowerPoint is well documented in this article.
