It has not happened to everyone when that they are working, for example, with some estimates above the browser window (which are visiting regularly just for calculations), and detest having searching the calculator application that is hidden again ?
Unfortunately, Windows does not include an option to keep the window always above the rest. That is something that solves TurboTop.
TurboTop is a very light application running in our application bar (system tray) of Windows, and allows us to force the application to stay on top of other windows. Thus, we can make the calculator application does not disappear behind the browser window, or whether we are using the Notepad, forcing it not to.
Simple, but very practical. They can be found here: Link
