What is Driver signing

The driver signature, also known as the driver's digital signature, was completed by Microsoft's Windows Hardware Quality Lab. Hardware developers will hand over their hardware and corresponding drivers to the lab, tested by the lab, and the lab will add a digital signature to its driver after the test is qualified. Because digital signatures are completed by Microsoft, users with digitally signed drivers will have the following benefits:

Security protection because the digital signature is for all software of the entire driver, any changes to the driver after the signature is completed will cause the signature to be invalid, thus avoiding the possibility of adding malicious programs such as malicious code propagation viruses to the driver.

Quality assurance previously said, any driver only through the Microsoft Quality Laboratory test to obtain digital signatures, so that the driver with digital signature is a good quality products.

Easy to install when the driver is installed, the Ghost Win7 system will be installed directly if the user uses a driver with a digital signature. If you don't have a digital signature, you can install it, but you'll get a lot of trouble.
