host regulatory system manages computers perfectly.With the launch of Microsofts 64-bit operating system
only signed drivers which cost money can be executed on windows x 64.For some reasons drivers cannot be signed so that host regulatory system is impossible for windows x 64.Unsigned driver problem becomes one of the most common problems
which lead to bad effect on portability or user experience
so it is urgent demand to execute unsigned drivers.In this paper
upon analysis of kernel assembler about verifying driver signature
we proposed a method to turn off the verification of driver signature.Then unsigned drivers can be executed.
