Enhanced Virtual Desktops is a program that permits you to have up to nine virtual desktops for better applications management.
This means that you can work in a more clean environment dividing active applications in more desktops.
This version of EVD contains a lot of new features like rules for starting applications, password for desktops or Active Desktop management and is more stable and compatible with third party applications.
After EVD starts you should see a small icon in the tray area of your pc (the right part of the Windows taskbar); simply left click on it to view all active applications or right click on it to show the menu and the options. By pressing SHIFT while clicking icon EVD will change desktop.
The green rectangle in the icon signals the current desktop (from left to right, top to bottom); the last desktop (9) is the right/bottom one ;-)
