I've a Logitech Media Keyboard 600 which features a separate button to launch the calculator. I need that quite often, but the Windows shipped calculator is useless; there are more advanced out there.

So I've installed another calculator application and want this special key start this other app instead of the default one.

Is that possible?

I'm not searching for a solution to pin the app to the taskbar and use another shortcut key to launch it.

Edit this registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\18\ShellExecute

If it does not exist, create a String Value with name ShellExecute and as value the path to your program.

Did you try Logitech's SetPoint software? It may not let you change what program the key opens, but it's worth a try. I don't have a Logitech keyboard, so I can't check.

You could also try replacing the Calculator executable (%windir%\system32\calc.exe) with the other calculator, but that may be risky.
