This is a cool one!!! If you have powertoys installed on Windows XP Its available for free at Microsoft website ( http://www.microsoft.com/windowsxp/pro/downloads/powertoys.asp ) . It is very easy to enable Microsoft Virtual Desktop Feature. Simply right click on the Start Panel Bar also called TaskBar, Click on Tool Bar and select Desktop manager. You would see a set of 5 icons placed on the right portion of the TAskBar. Click on number 1 to 4 to go to any of the desktops. Now you have have four different Active Desktops. IMPORTANT NOTE: You may see a little degradation in performance but for desktop work it is negligible.
