Window Hacker With this tool you can monitor all windows and child windows currently running on your computer. The application lets you enable buttons that previous wasn't enabled. In some cases you can disable nag screens from an application by making it invisible. If your computer is infected with a trojan virus, that has disabled itself on the taskbar and the Alt+Tab menu, hWnd will let you obtain the trojan window handle in the hWnd Lister and then you can send a WM_DESTROY message to destroy the virus! Previous this app was named "hWnd Monitor". Getting Started Window Hacker will start in a monitoring state, where the window currently under the mouse, is the one being shown. To start working with a window, you'll have to stop this monitoring, so it will be locked to just one window. You can do this by pressing F5, or use the global hotkey Ctrl+Shift+F12. Remember to keep the mouse over the window you wish to grab when doing this. It is also possible to grab a window to work with from the Enum or Branch tab.
