HP/Compaq :: How To Remap Quickplay Button Win 7

I had a registry hack to remap the quickplay button that worked fine under XP. This is the touch sensitive control at the top of my dv5t next to the mute, volume, play controls. Under XP the location was:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerAppKey18

But it doesn't appear to work under Win 7. Does anyone know the location for Win 7?

I don't want to install Quickplay, and didn't need to under XP. All the other buttons work fine out of the box.

I've seen two locations for Vista:

HKEY_LOCAL_MACHINESOFTWAREWow6432NodeCyberLinkQuickPlay
Change the key "Main" to the path of the program you want (sans the quotation marks if you copy it as a path). The original value of this is something like C:Program Files (x86)HPQuickplayOP.exe (no quotation marks). Replace that. I replaced it with C:Program Files (x86)Microsoft Origami Experience Pack 2.0Origami Experienceox.exe (Origami central executable).

and

You can reassign the quickplay button to open any program by changing the "QAction" value in [HKEY_LOCAL_MACHINESOFTWAREWow6432NodeHewlett-PackardHP Quick Launch Buttons].
