Software products licensed through a Microsoft Volume Licensing program are subject to Product Use Rights (PUR), which govern the use of the software.
Microsoft does not sell its products to customers. Instead, customers purchase the right to use the product in a specific manner. This is called a product license. All product licenses come with agreements that define and govern how you can use the software.When a product license is purchased through a Microsoft Volume Licensing program, its use is governed by the PUR document, together with the Microsoft Volume Licensing program agreement.
The PUR document contains the product-specific terms and conditions that govern how Microsoft products can be used in the Volume Licensing programs. It is the equivalent of the Software License Terms (formerly known as the End User License Agreement or EULA), that you receive when acquiring a retail product. Much of the wording is common to both the Software License Terms and the PUR.
This document is updated quarterly. The PUR that is in effect as of the beginning of the licensed period for a particular product version applies to the use of that product version throughout the licensed period. The use rights for a particular product version lock when a customer first orders a product. If a new version is released, use of the new version is governed by the most current PUR as of the time of that release.
