OEM Software Licensing: Rules & Restrictions
License Transfers*
OEM Software may NOT be transferred to another machine. Even if the original laptop, PC or Server is no longer in use, or if the software is removed from the original hardware, OEM licenses are tied to the device on which the software is first installed.
Microsoft Office and Terminal Services
OEM versions of Microsoft Office cannot be deployed in a Terminal Services or remote desktop services environment. When deploying Microsoft Office in a Terminal Services environment, the Office licenses should be purchased through a Microsoft Volume Licensing agreement.
Re-imaging*
Re-imaging rights are a benefit granted to Microsoft Volume Licensing customers. Volume Licensing customers may re-image any software they have legal licenses for (including Microsoft OEM Software) using Volume Licensing media.
Hardware Replacement*
The motherboard is the component that determines whether or not a new Microsoft Windows Desktop Operating System license is required. Motherboard upgrades or replacements require a new operating system license with an identical series motherboard (unless a replacement is for a defect).
Volume Licensing Customers
Windows desktop operating system licenses purchased through Microsoft Volume Licensing Programs are UPGRADES and require an eligible underlying Windows license (generally purchased as an OEM license pre-installed on a computer system).
Downgrade Rights*
Microsoft Office: OEM Microsoft Office licenses DO NOT grant downgrade rights. For eligible Microsoft Office licenses, Software Assurance can be purchased within 90 days through a Volume Licensing agreement. Software Assurance provides downgrade rights, home use rights, training, and more. Note: From the release of Microsoft Office 2010, Office is no longer available as an OEM license.
Microsoft Windows (desktop): Windows 7 Professional and Windows 7 Ultimate customers have downgrade rights to Windows Vista Business, Windows Vista Ultimate, or Windows XP Professional.
Microsoft Windows (server): OEM Microsoft Windows Server licenses DO grant downgrade rights. OEM versions released with, or after Windows Server 2003 R2 allow the end user to downgrade to an earlier version.

Transferring Licenses
OEM Software may NOT be transferred to another machine. Even if the original laptop, PC or server is no longer in use, or if the software is removed
from the original hardware, the OEM licenses are tied to the device on which the
software is first installed. As long as the license and device remain together, there is no limit to the number of times they may be transferred from one user to another. When transferring a PC to a new end user, the software media, manuals (if applicable), and Certificate of Authenticity label should be included. It is also advisable to include the original purchase invoice or receipt. The original end user cannot keep any copies of the software.
When OEM licenses have Software Assurance (SA) coverage: If an OEM license has SA coverage, although the SA coverage may be transferred the underlying OEM license may not. If any upgrades have been applied as part of the SA coverage, those upgrades must be removed before reassignment of SA to a new device.
