Driver Signing

Driver signing associates a digital signature with a driver package.

Windows device installation uses digital signatures to verify the integrity of driver packages and to verify the identity of the vendor (software publisher) who provides the driver packages. In addition, the kernel-mode code signing policy for 64-bit versions of Windows Vista and later versions of Windows specifies that a kernel-mode driver must be signed for the driver to load.

Note  Windows 10 for desktop editions (Home, Pro, and Enterprise) and Windows Server 2016 Technical Preview kernel-mode drivers must be signed by the Windows Hardware Dev Center Dashboard, which requires an EV certificate. For details, see Driver Signing Changes in Windows 10.

Kernel-mode driver binaries embed signed with dual (SHA1 and SHA2) certificates from a third party certificate vendor for operating systems earlier than Windows 10 may not load, or may cause a system crash on Windows 10. To fix this problem, install KB 3081436.
