  1. B107: An Overview Of Dung T. Thoi Microsoft Switzerland Level 100299

  2. What fuelled Windows 7 • Engineering Excellence • Developer Input • Customer Input

  3. Windows 7 Builds on Windows Vista… • Few Changes: Most software that runs on Windows Vista will run on Windows 7 - exceptions will be low level code (AV, Firewall, Imaging, etc). Hardware that runs Windows Vista well will run Windows 7. • Few Changes: Focus on quality and reliability improvements Deep Changes: New models for security, drivers, deployment, and networking

  9. Where Enterprise Data Lives MOSS 2007Team Sites HR Legal Sales Line of Business EMC Documentum Repository E-mail Corporate Index My Docs Intranet Internet Local Machine

  10. Federated Search Setup • OpenSearch protocol (http://opensearch.org) • Simple http protocol that builds on RSS & ATOM • 1-2 days to add it to a search server’s web front end • Supported by MOSS 2007 servers out of the box • No code installation required for client deployments 3. Deploy .osdx http request 1. Enable Servers for OpenSearch 2. Create .osdx RSS results

  13. Performance • Responsiveness to the user • Consumes resources from foreground applications • Boot, Shutdown, Logoff, etc. • Reliability • Memory leaks • System crashes, hangs • Dependent application crashes Impact Of Background Activity • Security • Activity may require system privileges • Successful attack may compromise entire system • Power Consumption • Extra disk, CPU utilization • Decrease in battery life • Prevents idle efficiencies

  14. Impact Of Background Activity • Internal evaluation of 49 Windows services • Not critical for boot and login • Critical and required for their individual scenarios

  15. Background Activity Performance Impact • Compared IT image to clean Windows Vista installation: • 10 additional 3rd-party services

  16. Designing For Efficiency • Choose the right model • Windows Service or Scheduled Task? • Leverage the latest Windows infrastructure • Trigger-Start Services for Windows 7 • Make performance optimizations • Eliminate unnecessary privileges • Evaluate and measure • Iterate (step 1)

  17. Trigger-Start Services • Device Trigger • Group Policy Trigger (machine & user) • IP Address Trigger (arrival & removal) • Domain Trigger (joint & removal) • Custom Trigger Service foo • Manual • Automatic • Device Trigger • Start Service • Stop Service • Device Interface ID • GUID • HW ID

  22. Direct3D Segoe UI DirectWrite Direct2D DirectX Technologies • Increased performance and visual quality (2x) • Lower CPU usage than GDI/GDI+ • Hardware accelerated • Reduced memory consumption DXVA & WIC

  23. Memory Usage In Windows VistaWindow with GDI content System memory allocation 1 GDI 2 GDI video memory allocation Provided by: Microsoft ISV DWM Composition IHV

  24. Memory Usage In Windows 7Window with GDI content System memory allocation 1 GDI 1 GDI video memory allocation WDDM Provided by: Display driver Microsoft ISV DWM Composition IHV

  25. Results Note: The above data compares system memory consumption only. Preliminary data gathered on Windows 7 pre-release builds and subject to change

  28. Performance Background Processing Graphics Power Efficiency

  29. Reduce Workload Power • Resource utilization optimizations • Reduce power by eliminating unnecessary activity • Examples: • Events and notifications instead of polling • Extending polling intervals • Eliminating periodic disk activity • Trade quality or performance for power savings • Examples • Index only high-priority items • Disable animations • DVD playback at 30fps instead of 60fps • “Race to Sleep” • Execute rapidly at high power • Quickly re-enter low-power state • Extend average idle duration • Examples • Timer coalescing Watts Idle Power Idle 0W - Off Time

  30. Power Efficiency – Timer Coalescing API • Platform energy efficiency can be improved by extending idle periods • New timer coalescing API enables callers to specify a tolerance for due time • Enables the kernel to expire multiple timers at the same time Timer tick 15.6 ms Vista Periodic Timer Events Windows 7

  31. Power Policy Enhancements • Iterative evolution of Vista power policy • Continue 3 plans: Performance, Balanced, Power Saver • Same toolset • Refined UI elements • New power settings for Windows 7 features • Minor changes to idle timeout defaults • Power WMI Provider • Enables power policy configuration through standard WMI interface

  37. PowerPoint Guidelines • Font, size, and color for text have been formatted for you in the Slide Master • Use the color palette shown below • See next slide for additional guidelines • Hyperlink color: www.microsoft.com Sample Fill Sample Fill Sample Fill Sample Fill Sample Fill Sample Fill

  38. PowerPoint TemplateSubtitle color • Example of a slide with a subhead • Set the slide title in “title case” • Set subheads in “sentence case” • Generally set subhead to 36pt or smaller so it will fit on a single line • The subhead color is defined for this template but must be selected; In PowerPoint 2007, it is the fourth font color from the left
