I often record desktop activities. Maybe you can try a good screen recorder alternative from Joyoshare VidiKit (originally Joyoshare Screen Recorder). It is available for Windows, including your mentioned Windows 10. Also, it allows you to customize capture area so you can record in full screen, preset ratio and designated size. If you'd like to edit, there are options to show clicks, highlight cursor, set shortcuts, embed watermark, schedule, trim, etc. The screen video with audio can be recorded in high resolution!
