Is there another key that could be overriding it?

[Ganesh Ujwal]

I used the ShellMenuView utility to find the registry keys associated with the .js extension and changed this key:

HKEY_CLASSES_ROOT\JSFile\Shell\Edit\Command
from a path to notepad.exe to the notepad++.exe path.

For some reason though the edit context menu still opens with notepad. I did the same thing for .bat files and it worked fine. Is there another key that could be overriding it?

A couple possible places. HKEY_CLASSES_ROOT\* applies to all files regardless of its type, if it hhas the same "edit" command there will be a conflict (I'm not sure which one takes precedence here).

Also, the route you pointed to are the global settings. There is also a per-user file associations located at HKEY_CURRENT_USER\Software\Classes. From there the very same structure follows. Entries from both places are considered to build the context menu, but for those that are duplicated, the per-user settings override the global ones, could be another place to look.
