Replace "Windows can't open this file" dialog

I need to replace the standard "Windows can't open this file" dialog that is shown on Windows 7 with my own program. If I remember correctly, on WinXP it was possible by modifying the HKEY_CLASSES_ROOT\* registry key, but it doesn't seem to work on Windows 7.
