I want to add some command line switches when calling a program via File association in Windows 7. This used to be possible in Windows XP, but I can't see how to do it in Windows 7.

I believe in xp you could accomplish this using a registry key, and that probably hasn't changed for Windows 7. Look for your extension in HKEY_CLASSES_ROOT. Unfortunately, I don't remember what the exact modification needs to look like.
