GetWindowText is a very small and portable program with which you can read the window text. By clicking the left mouse button on the button with GetWindowText icon and by holding down the left mouse button (drag), the read can be started.
Then simply hold your mouse over the window from which the text should be read. It can be read almost all the texts, e.g. from Edit, Static, Groupbox Controls. This program supports also directory trees (SysTreeView32) and list views (SysListView32) to read the entire contents. When you release the mouse button, the reading will be finished.
