Access to Prior Product Versions – September 2012 Update
Customers who have licensed software through a Microsoft Volume Licensing program are eligible to use prior versions of the software edition they have licensed. This is known as a "downgrade right." More information is provided in a Volume Licensing brief entitled, Downgrade Rights, as well as in the Product Use Rights and Product List documents.
If you have legally-obtained physical media (CD/DVD) of older licensed Microsoft products which your organization is currently licensed to use through downgrade rights, you may use these prior software versions at your discretion.
In general, the Volume Licensing Service Center (VLSC) provides download access only to the current (N) and the last version (N-1) of products. Note: In addition to VLSC download software access, Volume Licensing customers can order physical media (CD/DVD) copies of their licensed software through VLSC.
With the release of new product versions previously available products are removed from VLSC as they become N-2 versions. Support for physical media purchases of these N-2 products through Microsoft also ends at this time.
As of December 2012, a limited set of N-2 and N-3 prior product versions remain available for download through VLSC:
Note: In the event that Product Keys for N-2 versions that are listed above are not available from VLSC, please contact a Microsoft Product Activation Center.
If your organization continues to require access to specific prior version products, we recommend you first contact your Microsoft reseller to determine if they have still have media inventory. If you have received past shipments of physical Volume Licensing media (comprehensive or subscription kits) or have purchased physical CD/DVD media, you may continue to use these discs to install prior version products that are no longer available from VLSC.
