Windows driver and kernel program development have kept a mysterious veil since the birth of Windows, and have always been considered as relatively advanced technologies in the development field. It requires programmers to have a deep understanding of the underlying Windows operating system and rich debugging experience. But at the same time, many fields of computer need a large number of drivers and kernel developers, such as the driver design of PCI and USB devices. At the same time, with the widespread spread of computer viruses and Trojans, a large number of security-related software need kernel development technologies, such as process and thread monitoring, file and registry filtering, and such Rootkit prevention technologies. Due to the lack of drivers and core talents, it has always been regarded as a well-paid golden profession by others.
