Windows 7 Development: Background services (Hands-on labs)

Windows 7 and Windows Vista have undergone a lot of improvements in background processing. Today's challenges to achieving effective background processing include:

• Performance-start delay, logon delay, shutdown latency, background processing interferes with foreground processing

• Power consumption

• Security-Increased attack surface

Windows 7 Background services and scheduled tasks use a variety of mechanisms to minimize power consumption, reduce system attack surfaces, and improve application and system performance. These mechanisms include:

• Security permissions for service requests

• Service SID

• Delayed automatic start service

• Trigger Start Service

• Schedule Task conditions and settings

Due to the large number of services in today's Windows, background processing must meet security, performance, and power consumption requirements.

Goal

In this experiment, you will learn how to:

• Design and implement trigger initiation services

• Minimize the amount of permission on a service request

System Requirements

To complete this experiment, you must have the following software:

Microsoft Visual Studio 2008

windows 7

Windows 7 SDK

Windows Sysinternals Process Explorer

Set up

This experiment requires that the Windows 7 SDK be properly integrated with Visual Studio 2008. You can do this by following these steps:

1. Click the Start menu to go to All Programs | Microsoft Windows SDK v7.0 | Visual Studio Registration, and then click the Windows SDK Configuration Tool. On the Windows SDK Configuration Tool dialog box, verify that the v7.0 version is selected, and then click Make Current.
