Community Clips.
Community Clip is free software that allows you to capture all or part your desktop activities with keystrokes and audio. After installing Community Clip, it adds an option in Office Ribbon as well as in system tray. Community Clips can be used in capturing a part of desktop or full window for preparing how-to videos, recording step-by-step procedures, or you can use it for narration for adding audio to your powerpoints or other Microsoft programs to make a video explanations of your files/slies/graphs, etc. I find it similar to Jing, but faster to upload.
