If you are still using Windows XP/2003 - you may find useful the Window Thumbnails service which was presented in Windows Vista. Window thumbnail is a reduced window snapshot - looking at it you can quickly overview window contents on the whole and tell windows apart easier without the need to activate them. Once enabled, this feature creates a preview image for each running window and then displays this preview along with the regular popup hint in the following places:
- over regular Taskbar buttons and over Multi-monitor Taskbar buttons;
- over AltMin screen icons;
- over Virtual Desktops Switcher buttons.
This service highly increases the recognition of minimized or invisible windows without the need to restore them.
This feature does not work on Windows 2000.
Applications that were written without accurate conforming to the rules of development for Windows may be incompatible with this service.
