Installing and Managing Hardware
Lesson Summary
System Information displays configuration information about a computer. Most of this information is available in other utilities, but System Information consolidates it into a single source. You can document the system s current configuration by printing the System Information report or by saving the report to a file. Device Manager is the primary tool used for managing and troubleshooting hardware devices. Device Manager provides a central location to view the status hardware devices, enable and disable devices, change hardware settings, and troubleshoot hardware problems. Troubleshooters are special types of help files that pinpoint problems and identify solutions by asking you a series of questions.
Lesson 3 Supporting and Troubleshooting Device Drivers

Lesson 3: Supporting and Troubleshooting Device Drivers
Hardware drivers are software that governs the interactions between Windows and a hardware device. As a DST, part of your job will be to ensure that drivers are reliable and up-to-date. Device Manager provides a simple method of viewing and updating drivers for any device in the system. Windows XP also supports driver signing, which provides a method to verify that Microsoft has tested the designated device drivers for reliability.
