Downgrade rights for Windows 7 are an end-user right, documented in the Software License Terms that customers accept upon first running Windows software.
Note that Windows 7 end user downgrade rights will be available for approximately 18 months after the general availability of Windows 7 (April, 2011) or the release of a Windows 7 Service Pack, whichever is earlier.
- Purchase a PC preinstalled with Windows 7.
- Accept the Windows 7 Software License Terms.
- Perform the downgrade or authorize an Original Equipment Manufacturer (OEM) to perform it.
A system builder (when authorized by the end user) or the end user can install the software. A Windows XP Professional media disk is needed to facilitate the downgrade from Windows 7 Professional or Windows 7 Ultimate to Windows XP Professional.
The downgrade media can be media associated with any prior legally licensed version from the OEM system builder or retail channels. Additionally, an end user, who is licensed separately through Microsoft Volume Licensing programs, may provide their Volume Licensing media and key to their system builder to use to facilitate the downgrade on only their systems.
