What to Know about Downgrade Rights
The following provides more details on downgrade rights for Windows
Vista, Windows XP Professional, Windows Server 2003 Standard and
Enterprise Editions, and Windows Small Business Server 2003 Premium
Edition.
Also see the Downgrade Rights FAQ
· The right to downgrade is an end-user right and is documented in the
OEM System Builder product end-user license agreement or EULA.
· OEM System Builder Downgrade Rights for operating systems apply to
Windows Vista Ultimate, Vista Business, Windows XP Professional, and
Windows XP Tablet PC editions only. For Server, these rights apply to
only Windows 2003 Server Standard and Enterprise Editions and Windows
Small Business Server 2003 Premium Edition. OEM versions non mentioned
do not have downgrade rights.
· If the End User chooses this option, it is noted in the 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 Microsoft OEM
System Builder License). End Users can use one legal version of the
downgrade media for multiple installations. The end customer does not
need to have one set of media for each PC they are downgrading,
because they have acquired legitimate full operating system licenses
for the most recent version, which gave them the right to downgrade.
· 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 software may not be installed on any other computer system than
the one which was downgraded under this right.
· If downgrading the End User cannot use the downgrade operating
system (for example Windows XP Professional) and the most recent
version which they downgraded from (for example Windows Vista
Business) at the same time.
· If downgrading Windows Server 2003 or Small Business Server 2003,
the End User cannot use the downgrade server software and Windows 2003
software at the same time.
· If an End User chooses to downgrade to an approved, prior version of
the Windows desktop operating system, the PC Manufacturer is still
required to apply the desktop operating system Certificate of
Authenticity (COA) to the PC.
· End Users may reinstall Windows Vista Business, Vista Ultimate,
Windows XP Professional, Windows XP Tablet PC edition, Windows Server
2003, or Windows Small Business Server 2003 at any time, provided the
downgrade operating system has been removed from the computer, and
that software is reinstalled on the PC it was originally installed on
with the original OEM System Builder edge-to-edge CD distributed with
the original PC. The End User will need to use the Product Key,
located in the center of the Certificate of Authenticity (COA), in
order to activate the product.
· When an end user is using their downgrade rights offered under the
License Terms in Windows Vista Business and Ultimate versions and they
use both Windows XP media and a product key that was previously
activated, they will fail activation due to the hardware configuration
change when installing on the Vista system. In these cases the end
user will be prompted to call the Activation Support Line and explain
their circumstances to the Customer Service Representative. Once it is
determined that the end user has a valid Vista Business or Ultimate
license, the Customer Service Representative will help them activate
their software.
· For Client Access License (CAL) downgrades, end users may use
Windows Device CALs and Windows User CALs with an earlier version of
the software in accordance with the terms of the of the Windows Server
2003 EULA; however, due to technical incompatibilities, the end user
may not use TS Device CALs with TS User CALs.
This summary is intended to be a general informational overview of the
downgrade rights outlined in the End User License Agreement for the
indicated Microsoft OEM System Builder product. It is not intended to

this document is subject to change without notice. Please refer to the
actual EULA for the precise terms and conditions which govern use of

Downgrade Rights FAQ
Q. Who can install the Downgrade Software or reinstall the original
software?
A. A System Builder (when authorized by end user), or the end user.
Because downgrade rights are an end user right granted in the end user
license agreement (EULA), the end-user must first be able to accept
the (EULA) associated with the software, so this software must be
installed first before the Downgrade Software is installed.
Q. Do I need to ship media for the Downgrade Software system as well
as most recent version they are using to downgrade from?
A. The System Builder may not provide the end user with the Downgrade
Software media. This media must come from the end user and must be
legally licensed from the Microsoft retail, OEM/System Builder, or
volume license channels.
System Builders must provide the Windows Vista Business, Vista
Ultimate, Windows XP Professional, Windows Server 2003 Standard
Edition or Enterprise Edition, or Windows Small Business Server 2003
media that is located in the Microsoft System Builder Pack to the end-
user.
Q. Can end users use Windows Vista Business or Ultimate, Windows XP
Professional, Windows Server 2003, or Windows Small Business Server
2003 software and the Downgrade Software at the same time?
A. No. End users may only install and use one Microsoft operating
system (either the Downgrade Software or the applicable Windows Server
2003 software) at any given time.
Q. Can end users return to Windows Vista Business or Ultimate,
Windows XP Professional, Windows Server 2003, or Windows Small
Business Server 2003 software after they downgrade?
A. Yes. End users who downgrade may reinstall the original software
when they are ready to migrate. For example, an end user who
downgrades to Windows NT Server 4.0 may later return to the Windows
Server 2003 Standard Edition software provided that the end user
deletes Windows NT Server 4.0 software from the server.
Q. How do end users reinstall the original software after downgrading
to a previous allowed downgrade version?
A. End users must use the original System Builder media that was
included with the PC or server for reinstallation. The Downgrade
Software must be deleted from the hard drive before the original
software is reinstalled.
Q. Where do customers get the CD to install the Downgrade Software?
A. End users must use a legally licensed version of the specified
previous version of the Windows desktop or server operating system to
install the Downgrade Software. The Downgrade Software may be from the
retail, OEM/System Builder, or volume licensing channels.
