HP Pavillion Notebook Quicklunch Buttons.
Its the Quick Launch Button Control process for HP laptops / computers. If its causing problems, just end the process in task manager. It has prevented me from launching some apps (Supreme Commander - Forged Alliance). After killing the process - no worries

HP says: "This package enables customers to program the Quick Launch Buttons on the keyboard or to use the default settings"
It was using up 40% of my CPU so I terminated it. It did nothing to my computer, it still works. But now the fans aren't blaring!
