Explanation:
According to Microsoft KB: Windows 2000 systems will support the ability to either warn or entirely block users from installing unsigned code. If a file has not been digitally signed and resides in the above-referenced classes, users will be notified that a file has not been digitally signed, and prompted whether they would like to continue. Driver signing uses the existing digital-signature cryptographic technology. A hash of the driver binary and relevant information is stored in a catalog file (CAT file., and the CAT file is signed with the Microsoft signature. The driver binary itself is not touched; only a CAT file is created for each driver package. The relationship between the driver package and its CAT file is referenced in the driver’s INF file and maintained by the system after the driver is installed.
