Lesson 3 Updating drivers
Objective Update a driver.

Updating Windows Drivers for Windows

After a device driver is installed it is important to update it. As we discussed earlier, the most common cause of system crashes and lockups are faulty device drivers.
As you learned in the previous lesson, all hardware devices require a device driver to act as an intermediary between the hardware and the operating system. In this lesson, you will learn how to update drivers after they are installed.

Why update device drivers?

When a device driver is developed, it will typically be tested to ensure that it functions properly in most computer environments. Nevertheless, compatibility problems may still arise after a driver is released to the market. To address any issues that come up, manufacturers will release updates that fix any known problems.
As a result, you should make it a part of your routine to periodically check for and install updated device drivers. By doing so, you can eliminate problems that you have been experiencing with a particular device and/or prevent future problems.

Who can update drivers?

To protect the system from tampering, users cannot change drivers without having the appropriate rights. Usually, device drivers will be updated using the Administrator account. By default, the Administrator account has the right to:
  1. Load and unload drivers
  2. Copy files to the System32\Drivers folder
  3. Write settings to the registry
The steps required to update a device driver are shown in the following Slideshow.
In the next lesson, you will learn how to manage driver signatures.
