Many applications when installed in Windows also add their menus in the right-click context menu which appears when you make a right-click when selected a file or on desktop. This sometimes makes it very cluttered and even for a doing something small you need to move your mouse too high or low. Like you can see below :
Though there are many ways to clean this which includes registry  hacks but that is not recommended for non power users.
Menu Maid is one application which helps you clean of the cluttering using its simple configuration screen. It also can help you clean those extra menus which shows in the Internet Explorer.
It lists down all the applications which has registered with right-click and where they all get displayed. For example you might only want to see Dropbox context menu on directory and not on other clicks. All you need to do is uncheck and the menus will be gone from the respective places.
This application can be downloaded from here and if you are looking forward to make it more productive.
