In Windows 7,
My Screen Recorder Pro can record both the narration from your microphone and the sounds playing through your speakers. You will need to run the Tune Audio Wizard and make sure to select both. Here is information on using the
Tune Audio Wizard.
The click sound from your mouse can be turned on from your Control Panel. Click on the Sound icon and click on the Sounds tab. Under the Windows Explorer section select Start Navigation and set the click sound. To get keyboard click sounds, use the free software 'clickey'.
