After digging into process and id’s I was able to track down the Guid for the Microsoft LifeCam VX-1000 and inspect several settings assigned to it via the Windows Registry.
As it turns out, there is a very simple hack to use the Windows Live Call button for any program you’d like!
I don’t have time at the moment to write a script or a program for this, but you can manually configure your webcam to open a program. If it’s already open then pressing the Windows Live Call button will simply bring it back into focus.
So far, I’ve only tested this button to open and focus Digsby and Opera, but it could in theory be used to call and or focus any application.
If you’re a little sketched about editing your Registry then that’s a sign that this hack isn’t for you and you should wait until I (or someone else) releases a tool that suits you.
If you’re still reading, then you probably want to get rid of that annoying Windows Live prompt. 
- Open up RegEdit.
- Navigate through the Registry to the following location:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{6BDD1FC6-810F-11D0-BEC7-08002BE2092F}\0000\Settings - The key that you want to edit is conveniently labeled “QuickStartPath“.
- Just change this key to the direct path of any file you want to launch. You can test that it works immediately after saving the key. No need to close RegEdit until you’re done.
If it works, great! You’re done! If not, then you’ve done something wrong.
Remember that the original file that was being launched was something similar to “C:\Program Files (x86)\Microsoft LifeCam\icepick.exe” depending on your platform. Mine is 64-bit, so you’re may not need the “ (x86)” specific Program Files directory (if you’re using a 32-bit computer).
If I find some free time soon I may write a simple program that can be called to do more than just open your messenger. Possibly start a video chat with someone who just signed on. We’ll see in time.
Enjoy this little hack!
