I had a piece of software that required that I install QuickTime.
After installation I noticed that when I clicked on a wave file in Internet Explorer QuickTime would be activated to play the file. Previously, I would be given the option to save or play the file. If I chose play, it would be played via winamp. I uninstalled QuickTime. Now clicking on a wave file prompts me to install QuickTime. How can I restore my system to a pre-QuickTime condition?
