If your context menu in Windows Explorer and/or Internet Explorer is a little more cluttered than you'd like, Menu Maid makes entry removal easy.
Menu Maid allows you to circumvent the hassle of editing your registry to remove unwanted entries in the right-click context menus of Windows Explorer and Internet Explorer. While Internet Explorer only has one right-click context menu to alter, Windows Explorer has different contexts based on where you've right clicked or hit the applications menu key. Menu Maid can edit out context entries for everything, or just sub-contexts like directories and drives. Menu Maid is freeware, Windows only.
