The Microsoft Open License Program
Microsoft Open License Program (OLP) is a volume licensing program that allows you to purchase licenses for software products at a lower price relative to retail prices of boxed products. The program offers a full range of products for businesses: operating systems, desktop applications, server products, and development tools. For operating systems, a full license for Windows Professional GetGenuine and Windows Professional Upgrade licenses are offered. It has minimum license requirements and offers customers volume pricing with the flexibility to pay as they go. It allows them to acquire additional software products, as needed, to grow with their changing business needs. Open License offers a greater discount for a larger upfront order.
OLP licenses provide perpetual rights to use current and previous versions of products. Along with licenses, you can purchase a subscription to the Microsoft Software Assurance (SA) support program, which provides the right to upgrade to new versions of products and some additional benefits for a period of 24 months. At the end of 24 months, you can purchase individual licenses for SA renewal.
