A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
If you just want to get rid of the embedded information, it's pretty simple.
Save a copy of the original presentation to work on. Then simply select and ungroup each of the embedded objects.
