VistaAeroSwitch

VistaAeroSwitch is a straightforward application that gives you the possibility of toggling the Aero effect supported by Windows Vista. It can be seamlessly handled, even by users with little or no experience in software tools.
After a brief installation procedure, you are greeted by a standard window with a plain layout, representing VistaAeroSwitch's interface.
The "what you see is what you get" principle clearly applies to the app, since there are no other options available, besides the ones visible in the main frame. Turning on and off the Aero effect is easily done, by clicking one of the corresponding buttons.
In addition, VistaAeroSwitch reveals important information on the PC, such as the operating system name, Aero status, processor, clock speed and system memory.
VistaAeroSwitch barely uses CPU and system memory, so it doesn't interfere with the runtime of other active processes. It has a good response time and immediately applies changes to the desktop, without causing the operating system to hang, crash or pop up error dialogs; we have not encountered any issues during our testing.
On the other hand, the app is not compatible with all graphics cards (they must be supported by DirectX 9). Thanks to its intuitive layout and overall simplicity, VistaAeroSwitch can be handled by all types of users.
