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

Responsive & Ready

•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

Platform

Power EfficiencySoftware 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.

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 timeEnables the kernel to expire multiple timers at the same time

Timer tick15.6 ms

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

How Federated Search WorksRich client experience

Previews, metadata, drag-&-dropFamiliar Explorer paradigms

Simple & lightweight integrationNo client codeAny server platform

Standards-basedOpenSearch 1.1RSS & ATOM

AuthenticationIntegrated or custom

1. Search Connector (.osdx) Installed

2. Windows sends search terms as HTTP request

3. RSS results returned from server

Federated Search

Search providers should

• Accept URL queries• Example: http://www.contoso.com/q={searchTerms}• Return rich RSS results

Windows 7 enables this via

• XML description of search connector• Property mapping• Thumbnail & preview URLs• Custom view descriptions
