Instead of hacking the registry, you can use two different NirSoft
utilities to clean up the context menu. Sadly, some of the menu items
are implemented as Explorer shell extensions (like the “shellex” keys
we explained above), and some are implemented as regular context menu
items (like the regular “shell” keys we explained above).
The first tool we will check out is ShellMenuView, which allows us
to manage all of those “shell” key items with an easy to use interface.
Just browse down until you find the offending item, then click the
Disable button… which will actually create a LegacyDisable key just
like we explained in the manual section above.
