retail licensing revenue. 

Client operating income increased in fiscal year 2006 reflecting the increase in OEM revenue partially offset by a $224 million increase in sales and marketing expenses, excluding headcount-related costs, mainly driven by increased investments in partner marketing and Windows Vista pre-launch programs. Headcount-related costs increased 6% in fiscal year 2006 reflecting both a 13% increase in headcount primarily associated with Windows Vista and further investments in our sales and marketing organization, and an increase in salaries and benefits for existing headcount, partially offset by a decrease in stock-based compensation expense. Client operating income increased in fiscal year 2005 primarily due to an increase in OEM revenue and a $444 million decrease in stock-based compensation expense. These factors were partially offset by an increase in sales and marketing expenses associated with “Start Something,” a globally launched advertising campaign, marketing for security initiatives, and an increase in salary and benefits for new and existing headcount. The additional headcount for research and development was primarily devoted to the continued development of Windows Vista.

Server and Tools consists of server software licenses and client access licenses (“CAL”) for Windows Server, Microsoft SQL Server, Exchange Server and other server products. It also includes developer tools, training, certification, Microsoft Press, Premier and Professional product support services, and Microsoft Consulting Services. Server and Tools concentrates on licensing products, applications, tools, content and services that make information technology professionals and developers more productive and efficient. The segment uses multiple channels for licensing including pre-installed OEM versions, licenses through partners, and licenses directly to end customers. The licenses are sold both as one-time licenses and as multi-year volume licenses. Server and Tools uses product innovation and partnerships with information technology professionals to drive the adoption and sales growth of its products. 

Server and Tools revenue increased during fiscal year 2006 mainly driven by growth in SQL Server, Windows Server, and Core CAL. SQL Server 2005 and Visual Studio 2005 were launched in the second quarter of fiscal year 2006 and produced revenue growth in these product lines. Revenue is impacted by overall server hardware shipments which we estimate grew 11% to 13% in fiscal year 2006. Server and Server applications revenue, including CAL revenue, and developer tools, training and certification revenue grew $1.31 billion or 16% during fiscal year 2006. The results reflect broad adoption of Windows Server products, especially SQL Server, which grew over 30% for the year. Consulting, Premier and Professional product support services revenue increased $218 million or 15% primarily due to higher demand for services. In fiscal year 2005, Server and
