Lab Exercise 1303: Installing Device Drivers in Windows 2000/XP
Installing new devices under Windows 2000 and XP is easier than it has ever been Assuming, of course, that you re starting with compatible hardware, Windows 2000 and XP will detect the new device and install the correct driver with little prompting Often, Windows already has a usable driver and will install it without any action on your part If the device is not compatible with Windows, usually it is just a matter of updating the driver, using driver rollback, or adjusting the setting for driver signing As these operating systems continue to mature, more new devices will become available With that said, it s better to use the driver that came with the device, and better still to download the newest driver from the manufacturer s Web site
You should check for newer drivers periodically, even for devices that have been working fine Manufacturers occasionally release new drivers aimed at optimizing the device or enabling it to work with some new technology Keep in mind, however, that a new driver may cause unexpected problems with your operating system Because of this, Windows XP introduced a feature that enables you to roll back to the previous (working) driver if something should go wrong with a driver update Microsoft attempts to protect the system by qualifying devices and drivers through the Windows Hardware Quality Labs (WHQL) and digitally signing the drivers as approved for the operating system Driver signing allows you to configure how the system will handle the installation of untested drivers One of two wizards will assist you when you need to load a driver: the Found New Hardware Wizard or the Add New Hardware Wizard Windows starts the Found New Hardware Wizard when it discovers some new hardware device while booting If Windows has a driver in its database, it proceeds on its own If not, the Found New Hardware Wizard will prompt you for one The Add New Hardware Wizard enables you to add or update hardware manually at any time There s a lot of overlap in how the two wizards work, so you ll look at just the Add New Hardware Wizard, which you can activate at any time
