Definition of Downgrade Rights
The Downgrade Rights in the Windows XP Professional End User License Agreement (EULA) refers to the right for your customers to use a previous version of certain Windows software: Windows 2000 Professional, Windows NT Workstation 4.0 and Windows 98 (Second Edition). Windows XP Professional is the first ever Microsoft OEM license to include Downgrade Rights. Previously, Downgrade Rights have only been available via Microsoft Select, Open and full-packaged product licenses. Now with the launch of Windows XP Professional, customers can purchase the latest operating system, but run a previous version until they are ready to upgrade.
Downgrade Rights in Windows XP Professional give customers the best of both worlds.
How System Builders Benefit
Customer Requirement: Your customer wants to purchase a new computer system but needs it to run the same operating system as their 10 existing systems - Windows 2000 Professional - until the whole office is ready to upgrade to Windows XP Professional.
Solution: You can preinstall Windows XP Professional on the new computer system, and then offer the additional service of installing Windows 2000 Professional on your customers behalf. Your customer can run Windows 2000 until it is ready to upgrade the systems to Windows XP Professional.

What to Know about Downgrade Rights
OEM Downgrade Right is an End User right.
OEM Downgrade Rights apply to Windows XP Professional only.
Identified downgrade versions of Windows XP Professional are limited to Microsoft® Windows® 2000 Professional, Microsoft Windows NT Workstation® 4.0, or Microsoft Windows 98 (Second Edition).
If the End User chooses this option, it is noted in the Windows XP Professional Product EULA that neither Microsoft nor the Manufacturer will supply such End User with media for such previous versions. The End User must provide the downgrade media and a valid Product Key.
End Users can use the following media for their downgrade: Volume Licensing media (provided End User has a Volume Licensing agreement), Retail (Full Package Product), or a system builder edge-to-edge CD (provided software is acquired in accordance with the Preinstallation and Distribution Agreement).
In the event the End User opts to downgrade, neither Microsoft nor the PC Manufacturer is obligated to provide customer product support for Customer Systems on which such previous versions are installed.
The Windows XP Professional software may not be installed on any other computer system than the one which was downgraded under this right.
The downgrade operating system is governed by the Windows XP Professional EULA.
The End User cannot use the downgrade operating system and Windows XP Professional at the same time.
If an End User chooses to downgrade to an approved, prior version of the Windows operating system, the PC Manufacturer is still required to apply the Windows XP Professional Certificate of Authenticity (COA) to the PC.
End Users may reinstall Windows XP Professional at any time, provided the downgrade operating system has been removed from the computer, and that Windows XP Professional is reinstalled on the PC it was originally installed on with the original recovery media or OEM System Builder edge-to-edge CD originally distributed with the PC. The End User will need to use the Windows XP Professional Product Key, located in the center of the Certificate of Authenticity (COA), in order to activate the product.
