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 Afraid of technology Learning curve too steep Afraid it won’t work with my existing system

Customers Expect Better Reliability Frequency of Crashes % of Customers % Very Satisfied 00%- 133%70% 219%53% 312%39% 48%40% 56%35% >523%26% 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 Crash frequency highly correlated to customer satisfaction As crashes increase, customer satisfaction decreases

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

Device Software Lifecycle

“Rule of thumb: A defect that costs $1 to fix on the programmer’s desktop costs $100 to fix once it is incorporated into a complete program and many thousands of dollars if it is identified only after the software has been deployed in the field.” Building a Better Bug Trap – The Economist June 2003

Microsoft Remains Committed to help You “Build It Right” Windows Driver Models Windows Driver Foundation Windows Driver Kit Enabling:  Faster and better design  Easier development  Simplified testing
