Introduction

The Windows client OS remains Microsoft’s most widely used software and consequently weighs heavily in any organization’s licensing decisions.

Windows 7 generally follows a per-device licensing model: The PC where it runs requires a license. While simple in theory, there are many license acquisition and compliance issues unique to Windows 7. Issues arise because most customers initially obtain Windows client licenses from their PC hardware manufacturer rather than directly from Microsoft, as is the case with other products. Microsoft has also chosen to offer a variety of special use rights to Software Assurance (SA) customers only. This complicates the decision of whether to purchase SA, which can be costly but which also delivers a special Enterprise edition of Windows 7 with extra management and other capabilities, as well as support and training services.

Because new PCs generally come with Windows, Microsoft volume licensing programs play a smaller role for Windows than they do for other products, such as Office. However, some Windows-related purchases are best made through these programs, and choosing the right program can help organizations strike the right balance between cost, commitment levels, compliance, and payment structures.
