  2. Session Outline • Introduction • Challenges • Opportunities to work together • What we are going to do • Provide tools across the lifecycle to help • Make driver “signing” worth something • What this means to you • Rapidly build high quality 32- and 64-bit drivers • Utilize Microsoft’s resources and investments • Expand to new markets • Summary/Call to Action

  3. Opportunities Abound …

  4. … but Fundamental Challenges Remain Let’s partner to nail the fundamentals • Build it right • Keep it right Reliability Users still reporting driver crashes through Windows Error Reports Simplicity Study* cites user experience between PCs and devices still too complex Deployment Microsoft Desktop Advisory Council reports driver deployment still a issue Source: “Ease of Use / PC Quality Roundtable” http://www.eouroundtable.com

  5. Real People, Real Life

  6. Impact to Our Industry • Key reasons consumers choose not to purchase new technology products: • Afraid of technology • Learning curve too steep • Afraid it won’t work with my existing system Source: Microsoft Primary Research project, 2004 Base: Adult Consumers who have not purchased item Q12A-D. For each of the following, please indicate the main reasons why you haven’t purchased any of these types of items in the past twelve months? Multiple responses allowed

  7. Customers Expect Better Reliability Crash frequency highly correlated to customer satisfaction As crashes increase, customer satisfaction decreases Question: On average, how many times per month does Windows crash or experience serious bugs? Question: Rate your overall satisfaction Source: Microsoft January 2003 survey of 754 homes and 503 small businesses

  8. Unreliable Equals Expensive • A large OEM did a study of blue screen-related calls • Results found: 6 crashes equals 1 technical support call Derived Crash to Support Cost Ratio (@ $10/call) Crashes

  9. Let’s Come Together, Work Together Our investments are based on partner feedback Microsoft is investing in tools and infrastructure Improved fundamentals are essential for great user experiences Maximize the potential of devices on Windows
