Windows 7 Cascading Context Menu

Description

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

Example Scripts

This example creates a cascaded context menu for the NSIS compiler, and if present also for the Unicode version of NSIS. The entries will be added to HKCR.

This alternative version will add the keys to the CommandStore of HKLM instead.

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.
