TopMost is a free, open source application that allows you to keep windows always on top of other windows.
This is very useful when you have an application that is maximized and fills the screen. You want to see it, work on it, but also use and see another smaller application.
For example, imagine reading a document and wanting to use some of the numbers in it in a calculator application. You would like to see the document and the calculator at the same time, to copy information from one to the other. In order to do it you should arrange the windows accordingly, often leading to minimizing the size of the document and making it hard to work with it.
Using TopMost you don't need to do it :) Just have the calculator stay on top of other applications and work on both.
TopMost works on all windows platform (XP, Vista, Windows 7, 32 or 64 bit).
