I’ve got a passthrough NDIS intermediate driver, consisting of two .inf files (one standard and one miniport) and a .sys file. Because of the Windows 7 driver signing requirements, I had to get a code-signing certificate and sign the .sys file in order for the driver to install on a 64-bit system. This works fine, and I have many successful Windows 7 installs.

However, the same installer fails on the Windows 8 Consumer Preview (64-bit). If I boot with Windows Signature Enforcement turned off, it installs correctly, so it’s definitely a signature issue. What new requirements were added between Windows 7 & Windows 8 that I need to follow in order to get my driver to install?

    Regenerate your cat file(s) so that they comply with the signing requirements for the new Window OS.

    For example, in my build script I had to add 8_X86,8_X64 to my inf2cat command:

    inf2cat /driver:"%CD%" /os:XP_X86,XP_X64,Vista_X86,Vista_X64,7_X86,7_X64,8_X86,8_X64

    For Windows 8.1, you will need the inf2cat included in Windows Driver Kit (WDK) 8.1 and depending on your target(s) add 6_3_X64, 6_3_X86, or 6_3_ARM to the /os:WindowsVersionList.

    Reference, Inf2Cat
