7 Ways on Windows 7 Fundamentals Libraries Taskbar Ribbon Sensor and Location Multi Touch Graphics *AppCompat*

Improved Fundamentals IncreaseDecrease

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 well. Windows 7 Few Changes: Focus on quality & reliability improvements Windows 7 Builds on Windows Vista Deep Changes: New models for security, drivers, deployment, & networking

Improved Fundamentals Compatible & reliable Designed to run on the same hardware as Windows Vista Drivers & Applications backward compatible Stable & secure Improved Security & UAC Windows Filtering Platform Responsive & Ready Building Power Efficient applications Service Control Manager Windows Troubleshooting Platform

Extended operation on battery power Leverage latest energy-efficient hardware New infrastructure & tools for developers & testers Power Efficient applications Trigger-starting of system services Service Control Manager Automated troubleshooting problem resolution Highly configurable & integrated with Windows 7 Solution Center Windows Troubleshooting Platform

Software performance = Power Efficiency “All day” mobile PC battery life TCO – reduced cost of energy consumption New power consumption regulatory compliance Environmental consortiums for computing (Green Computing) Windows 7 power optimization Less than 2% CPU activity when the system is idle No disk activity when the system is idle Reduced number of OS activities that prevent use of CPU’s power-saving modes.

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 BOOL WINAPI SetWaitableTimerEx( __in H&LE hTimer, __in const LARGE_INTEGER *lpDueTime, __in LONG lPeriod, __in_opt PTIMERAPCROUTINE pfnCompletionRoutine, __in_opt LPVOID lpArgToCompletionRoutine, __in_opt PREASON_CONTEXT WakeContext, __in ULONG TolerableDelay ); BOOL WINAPI SetWaitableTimerEx( __in H&LE hTimer, __in const LARGE_INTEGER *lpDueTime, __in LONG lPeriod, __in_opt PTIMERAPCROUTINE pfnCompletionRoutine, __in_opt LPVOID lpArgToCompletionRoutine, __in_opt PREASON_CONTEXT WakeContext, __in ULONG TolerableDelay );

Improved Fundamentals Power Management Demo

Impact of Background Activities Hundreds of Activities in Your Background Long running services affect the system PerformanceReliabilitySecurity Power consumption

Short Lived Services Equal… Better Performance Improves responsiveness to the user Results in shorten Boot, Shutdown, Logoff, etc times Better Reliability Reduce memory leaks Reduce the total amount of system crashes, hangs Better Security Have smaller attack surface Less Power Consumption More efficient CPU utilization Increase battery life by reaching idle state faster for longer periods

Trigger Start Services SCM registers for system events via providers: Device arrival IP address Domain join & leave Group policy updates Custom ETW (Event Tracing for Windows) events SCM starts or stops registered services: TabletInputService started only if digitizer is present StorSvc starts when group policy updates are applied, automatically stops

Task Triggers & Conditions Task Triggers Calendar Boot Logon Idle Event log based entry Workstation lock Workstation unlock Task Conditions Idle condition Stop when not idle AC power only Stop on battery Wake computer from sleep Specific or any network connection

Service or Scheduled Task? Windows Service Continuous activity from boot to shutdown Service Control Manager (SCM) programming model Can specify dependency Continuous activity from boot to shutdown Service Control Manager (SCM) programming model Can specify dependency Scheduled Task Short duration action Idle activity Take action on user login Standalone executable or out-of-process COM server Generally execute in user session Short duration action Idle activity Take action on user login Standalone executable or out-of-process COM server Generally execute in user session

Improved Fundamentals Converting a Service to Trigger-Start Service

Windows Troubleshooting Platform Troubleshooting Packs are Launched by user or application Detects & resolves configuration issues Verifies that configuration has been set properly Troubleshoot config Verify if desired user state can be supported Set configuration to support desired state

Provides secure (free) 3 rd party access to Watson events Enables ISVs, IHVs, & OEMs (over 2,200) to: Access Failure event data Quickly prioritize work to fix crashes Easily identify security related events! Easily register a response Supported Events 32, 64-Bit Crashes Special Exceptions Buffer Overrun Data Execute Prevention (NX) Windows Mobile Events Windows Vista “Hung Application” event “Generic Events” – Instrumentation defined by partners Developer Portal Web Services Provide programmatic access to event lists & crash dumps Client implementation shipping as an open source component on CodePlex Windows Error Reporting

Call to Action: Fundamentals Read the application quality cookbookapplication quality cookbook Make your application Windows 7 compatible UAC aware, Support x64, Sign files & drivers, no OS version checking, support multi user sessions…. Install to correct folders / transactional uninstall Self Certified with new Logo automatic tool Windows 7 resources optimization Power aware Retire old “XP” services to Windows 7 tasks Use triggered Services Provide troubleshooting pack & WER

Libraries and Search

Windows 7 "New" Explorer

Libraries New entry points to user data i.e. FOLDERID_ MusicLibrary Collections of user folders Common store Each folder is indexed Storage backed Default save location Work like folders

Libraries Your application should Support open & save in libraries Select & consume library contents Stay in sync with library locations e.g., Windows Media Player Windows 7 enables this via Common File Dialog Native: IFileDialog Managed: System.Windows.Forms.FileDialog Shell abstractions (i.e., IShellFolder) New Library API to manage libraries

Windows API Code Pack for the.NET Library Managed class library to access to Win 7 features Windows Shell namespace Windows Vista and Windows 7 Task Dialogs. Support for Shell property system. Taskbar Jumplists, Icon Overlay and Progress bar. Common file dialogs Support for Direct3D 11.0 and DXGI 1.0/1.1 APIs. Sensor Platform APIs Extended Linguistic Services APIs

Federated Search Consistent experience across providers Document Repository Enterprise Data Store Enterprise Application

How Federated Search Works Rich client experience Previews, metadata, drag-&-drop Familiar Explorer paradigms Simple & lightweight integration No client code Any server platform Standards-based OpenSearch 1.1 RSS & ATOM Authentication Integrated or custom 3. RSS results returned from server

Federated Search Search providers should Accept URL queries Example: Return rich RSS results Windows 7 enables this via XML description of search connector Property mapping Thumbnail & preview URLs Custom view descriptions
