GetWindowText is an extremely small and portable utility that allows you to read almost all the window text, from Edit, Static, Groupbox - Controls, and more.
By left-clicking the mouse on the button with the GetWindowText icon and holding down the left mouse button (drag), the read can be started. After that, you hold your mouse over the window from where the text should be read.
This program also supports directory trees (SysTreeView32), Combobox, and list views (SysListView32) to read the entire contents. When you release the mouse button, the reading will be finished.
