When you have a dozen different applications running at the same time on your computer, you need something else than just a simple icon when using Alt-Tab to switch between them.
With VistaSwitcher you get exactly what you're looking for: a full, real-time preview of all currently active apps and windows on your system, every time you press the Alt-Tab hotkey. VistaSwitcher enables you to switch between apps and windows in a much more comfortable way, knowing exactly what's running on your system and where you're headed to.
You can configure VistaSwitcher to replace the standard Alt-Tab combination, or use it as just an extra way to switch between programs. The program can be launched not only via Alt-Tab, but also with a customizable keyboard hotkey and VistaSwitcher's icon on the system tray.
The program includes a configuration menu to tweak its behavior and appearance. You can also filter specific applications so that they're not included in the Alt-Tab menu.
Need a more powerful, visual way to switch between active apps and windows on your system? VistaSwitcher is the program you're looking for.
