The desktop operating system licenses bought under any Volume Licensing Program are upgrade licenses only.
Full desktop operating system licenses are not available under any of these programs. Therefore, each desktop for which you acquire and on which you will run the Windows 7 Professional Upgrade must be licensed to run one of the qualifying operating systems identified below.
Windows 7 Professional Upgrade
Customers who wish to acquire the Windows 7 Professional Upgrade license must first have licensed and installed on their desktop a qualifying operating system.
Qualifying OS Rules (Each of these conditions must be met in order for the base OS to qualify you for the VL Upgrade.):
- The qualifying OS must be installed on the device to which the VL Upgrade license is to be assigned.
- Except as provided below, you must remove the qualifying Operating System from the device in order to deploy the VL Upgrade license.
Customers who wish to install or run more than one licensed OS at one time (including the qualifying OS), may either:
- Acquire Software Assurance for their VL Upgrade license
- Purchase full Windows 7 licenses separately via another channel
Note: Customers that have active Software Assurance coverage do not need to uninstall the qualifying OS and may install and run the qualifying OS and Windows 7 at the same time.
The choice of Qualified Base license depends on:
- The Agreement type and version
- If its a new or existing Agreement
Any operating system not listed above is not a qualifying OS, for example:
- Embedded Systems (e.g. Windows 9.x for embedded, Windows XP embedded) do not qualify for the Windows 7 Professional Upgrades
- Linux or OS/2 do not qualify for the Windows 7 Professional Upgrades.
- Windows Terminal Services Client Access License does not qualify for the Windows 7 Professional Upgrades
