This freeware application lets you configure any right-click menu, no matter which file you right-click on, just by dragging and dropping. You can remove menu-items you never use (like third parties advertisements) or put rarely used functions out on a sub-menu.
How to use it? Download (857Kb) and install it. Right click any file or items. You can see a colored bar in the right-click menu. Drag menu-items you never use to the Hidden items and drag the items you use occasionally to the Rarely used sub-menu (see image). Keep only those items you often use in the root-menu (the left side). Click Apply when you are done.
The program is tiny and takes very little system resources. The only disadvantage is that it displays a colored bar in the context menu, that is annoying, at least for me.
