How to Factory Restore a Dell Vostro 400
The Dell Vostro 400 Mini Tower computer is specifically designed for small businesses. It comes with generous amounts of RAM and hard drive space, no pre-installed programs and 10 total USB 2.0 ports so you can connect a large number of devices. Each Vostro 400 also comes with Dell's Factory Image Restore program that can restore the computer back to its original factory settings. This process erases all information on the hard drive, so it is only useful as a last resort when the computer has significant software issues.
Windows Vista and 7
