Windows 7 Cascading Context Menu

Description

As of Windows 7, one can create cascading context menus through the registry.

Example Script

This example creates entries for the NSIS compiler for all file-types. It is yet uncertain if this can be limited to a single filetype only.

Alternative Method

The MSDN forums mention an alternative method for creating cascading menus. This will create keys in the CommandStore (HKLM) rather than in HKCR.
