ShoWin displays useful information about windows by dragging a cursor over them.
Perhaps one of the most popular uses of this program is to display hidden password editbox fields (text behind the asterisks *****). This will work in many programs although Microsoft have changed the way things work in some of their applications, most notably MS Office products and Windows 2000. ShoWin will not work in these cases. Neither will it work for password entry boxes on web pages, at least with most web browsers.
Additional features include the ability to enable windows that have been disabled, unhide hidden windows (try the program with the include invisibles option set and see how many windows you have on your desktop that you didnt know about!) and force windows to stay on top or be placed below others.
