launching MATLAB from the context menu (Windows 7)

For several years I have been using the following hack, in windows, for convenience. Add the key:
and set the value to
With this, I was able to right-click on any file and launch MATLAB with that file's directory being the current directory. Just a simple trick for saving a fraction of a second several times a day.
This hack doesn't work since I installed R2011b. Any ideas why? I can still run MATLAB by opening a Dos window in any directory and typing matlab.
Thanks (Windows 7 64 bit, R2011b)

Found it. Apparently previous versions of MATLAB installers added the full path of the MATLAB runtime to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths
automatically, while the newer version didn't. So the above hack would work if we use the full path instead of just "matlab.exe"
