1 Dung T. Thoi Microsoft Switzerland Level 100  299

2 Customer Input Developer Input Engineering Excellence

3 Few Changes: Focus on quality and reliability improvements 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. Deep Changes: New models for security, drivers, deployment, and networking

30 Time Watts 0W - Off Idle Power 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 Idle Resource utilization optimizations Reduce power by eliminating unnecessary activity Examples: Events and notifications instead of polling Extending polling intervals Eliminating periodic disk activity

31 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 Periodic Timer Events Windows 7 Vista

32 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

39 PLEASE READ (hidden slide) This template is designed for use with Office PowerPoint The charts and graphics can be edited with PowerPoint 2007, but not with PowerPoint This template uses Microsoft’s corporate font, Segoe and Segoe Semibold Segoe is not a standard font included with Windows, so if you have not already done so, you need to install it on your computer How to install Segoe: Get the font at: \\Showsrus\images\Corporate_Fonts\PC\Segoe or https://mediabank.partners.extranet.microsoft.com Copy all the.ttf files into your c:\windows\fonts folder Questions:

40 Notes (hidden) Some speakers at Microsoft like to use this slide for hidden “notes slides”. Delete it if you don’t want to use it. NEXT:

41 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: Sample Fill

42 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
