What makes SwitchIt unique is that unlike other 'dual boot' products, SwitchIt allows you to refresh your second system to a clean working copy and you do it without ever leaving the Windows environment.SwitchIt is a program that allows you to Switch back and forth between your primary Windows system and a created second duplicate of that system. For the newer home systems where hard drive space is not an issue this program is a must. SwitchIt will maintain a second working copy of your Windows and Program Files directories.
