Aside from the driver management options found on the Driver tab, you can also verify driver signing in Windows Vista Driver signing, first introduced in Windows 2000 systems, enables you to make certain that you are installing and using only drivers that have been signed, or certified, by Microsoft This feature makes certain that the drivers have been tested and will work with specified hardware on Windows Vista The signing feature, however, certainly does not mean that unsigned drivers are damaging to your system or will not work it just means that Microsoft has not approved or tested them, and you are on your own in terms of testing, compatibility, and troubleshooting

Signed drivers have a digital signature stamp that cannot be altered without altering the entire driver package The digital signature is basically a digital code that is able to verify that the driver package comes from a reliable source This feature tells you that a signed driver is, in fact, a signed driver and that you can feel safe when using the driver on your system Another advantage of signed drivers, especially with Internet downloads, is that a signed driver tells you that the package is actually a verified driver not a virus or other malicious code acting like a driver For downloads of drivers, the signed driver feature can certainly give you a measure of protection The basic rule to follow is to use signed drivers if at all possible With the signed driver, you can ensure that the driver has been tested and has received Microsoft s seal of approval Of course, in some cases, it may not be possible to use a signed driver This is fine, but it leaves you doing your own homework to determine if the driver will work and if the driver is safe to use You can also use the File Signature Verification utility to check existing files on your computer in order to make certain that they are digitally signed Sigverif doesn t test a file to see if it has been modified, but it does check all installed drivers and reports which ones are signed and which ones are not signed For the exam, keep in mind that sigverif does not solve any problems It only generates a report You must review, analyze, and correct any perceived problems regarding unsigned drivers So how does all of this work Windows Hardware Quality Labs (WHQL) is the testing facility for signed drivers Third-party developers supply the hardware device and the proposed driver (along with payment) to WHQL If the driver doesn t cause OS problems, MS embeds a digital certificate into the driver file itself that includes a hash of the file This hash is like a fingerprint of the file If there is even a single bit changed, the hash will be different and can be used to identify file modifications, virus infections, etc This digital cert plus the hash become the digital signature used in driver signing The point here is that drivers have to be submitted and developers have to pay for the testing, so don t assume that all unsigned drivers are bad ; they may just not have been tested by Microsoft You can search for files, and you can also configure the tool to create a log file Exercise 3-5 shows you how to use the File Signature Verification utility
