Add Microsoft Software Assurance to your Volume Licensing agreement and move up to Windows 8 Enterprise. Software Assurance is a cost-effective program that provides new product versions and exclusive technologies—including Windows 8 Enterprise edition and the Microsoft Desktop Optimization Pack (MDOP). Software Assurance also helps you use IT to maximize your productivity with deployment planning, training, and support benefits.
Windows 8 Enterprise
Windows 8 Enterprise is available exclusively as a benefit of Microsoft Software Assurance through Volume Licensing programs such as Select Plus, Enterprise Agreement, and Enterprise Subscription Agreement.
Your IT professionals can download Windows 8 Enterprise from the Microsoft Volume Licensing Service Center (VLSC) and deploy it on your organization’s computers.

Only certain editions of the Windows operating system qualify for upgrades under Volume Licensing agreements. The table below lists the qualifying editions of Windows eligible for the Volume Licensing upgrade under each Volume Licensing program.
If your OS license qualifies, you can purchase the Windows 8 Pro Upgrade license, under your Volume Licensing agreement. It is important to understand that Windows licenses that are available through Volume Licensing are upgrade-only licenses and can only be acquired on top of a base OS license. These licenses are not a replacement for a pre-existing full OS license.
The following conditions must be met for a licensed PC to be eligible for a Volume Licensing upgrade license:
