Downgrade From Microsoft Windows Vista to Windows XP

When a Dell computer operating system has been modified outside of the factory, it will no longer be supported by Dell. In that case, contact the operating system manufacturer. Dell remains available to troubleshoot problems on a fee basis.

Changing the operating system from Windows Vista to Windows XP, a process called "downgrading," involves the following main steps (click the steps to expand for more information on the topic):

  1. Determine driver availability for Windows XP

    If downgrading a Dell computer with Windows Vista installed at the factory, make sure drivers are available at Drivers and Downloads.
    Also, for any components installed after you purchased the computer, make sure drivers are available for those by contacting the manufacturer. Many manufacturers provide driver information on their Web sites.

  2. Consider software compatibility

    Many software applications work on either Windows Vista or Windows XP, but not necessarily both. Contact the manufacturer of the software application. Many manufacturers provide operating system compatibility information on their Web sites.

    Find out if the software is Windows XP-compatible using one of the following methods:

    • Read the system requirements on the package to see which operating systems the software will work with.
    • Find the system requirements on the Web site to learn what operating systems are compatible with the software.
  3. Acquire the Windows XP operating system media and license

    Before downgrading the Windows Vista operating system, you must acquire an authorized version of the Windows XP operating system. Be sure to get the full operating system, not an upgrade. A full install is required.
    Downgrading to Windows XP requires using the Windows Vista installation disc. Use a copy made from backup, or acquire another copy.

  4. Back up the hard drive

    It is recommended that you back up all user data prior to proceeding with the operating system installation to avoid any possible loss of data.

    Replacing the operating system will result in the complete erasure of all data on the hard drive. Be sure to back up the hard drive in its entirety.

    The most common locations for user data include: e-mail folders, address books in Outlook®, My Documents folder, Desktop, Favorites, Web browser bookmarks, and any other data that you find useful.

    For more information about backing up data, refer to the following Microsoft Knowledge Base articles:
  5. Remove most external devices

    In order to complete a clean install, be sure to remove any unnecessary external devices. Removing unneeded devices will help to minimize the opportunity for any unexpected events.
    The following is a list of devices that should not be removed:
    • Monitor
    • Keyboard
    • Mouse

    The following are examples of devices that need to be detached:
    • Scanner
    • Printer
    • Portable handheld devices
    • Other external devices
  6. Perform a clean installation
    When the computer is prepared for the downgrade, the following steps walk you through the process of partitioning, installing, and setting up the Windows XP operating system:

    This process may take 30 minutes to 90 minutes. During this process, your system restarts once but should otherwise not be turned off or restarted.
