Downgrade the Microsoft® Windows 7 Professional / Ultimate installation to Microsoft® Windows XP.

According to the Microsoft® Windows 7 Professional / Ultimate EULA (End User License Agreement) that the computer user must read when starting up a new computer, the following Operating System downgrade rights are available:

  • Downgrade rights for Windows 7 are an end-user right, documented in the Software License Terms that customers accept upon first running Windows software.
  • Windows 7 end user downgrade rights will be available through the sales lifecycle of Windows 7 which is up to two years after the launch date of a new version. 
    UPDATE:  As of November 2012, Microsoft has upgraded their Windows Lifecycle information, indicating that this upgrade right expires in February, 2014.

More information is available from the Microsoft Windows web site and from the attached document.
