Installing and Running Windows Vista

When you install Windows Vista on a computer with an existing operating system, you can either perform a clean installation or an upgrade. With a clean installation, the Windows Vista Setup program completely replaces the original operating system on the computer, and all user and application settings are lost. With an upgrade, the Windows Vista Setup program performs a clean installation of the operating system followed by a migration of user settings, documents, and applications from the earlier version of Windows. Setup migrates previous settings because Windows Vista doesn’t store user and application information in the same way as earlier versions of Windows do.
