What RegKey can you get the default browser application's path from?
Best way to get to it from C#/.NET?
Here's the key you want:
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\http\shell\open\command
And here's a quick registry tutorial for C#, if you need it.
Edit:
For per-user settings, use this key:
HKEY_CLASSES_ROOT\http\shell\open\command
(HKCR has both machine and user settings, user takes priority).
Note that this might not work on Vista. For more info, see here.
