This is known as the "High Definition Audio Property" program and it is part of the windows operating system. If you don't have high definition audio on your computer then I would not worry about it.
Are you sure you meant to ask this question here? You mention our class. Is this one of CNET's online courses? If so, they have there own forums where students can ask questions.

In your class on speeding up XP, lesson #4 shows how to clean up your background programs. It said to leave HDAShCut alone. But it is not running on my computer. How do I get it to run? And what does it do? Thanks
