I tried to make this work on multiple occasions but I was never able to. If you really need to make new kernel-mode drivers for Windows Vista 64-bit, you might try instructing your users on how to disable driver signature enforcement. The friendly driver installation prompt for signed driver packages in Windows 8 looks pretty much the same as it did in Windows Vista and 7. Since the number of people using Windows Vista is pretty small these days, you can simply put a note in your documentation that tells Windows Vista users to make sure they have that update installed. If your certificate uses SHA-2 or has SHA-2 certificates in its chain of trust, then you should be aware of KB , an update for Windows Vista SP2 distributed through Windows Update.
Generally, you will know that you are testing executables correctly if Windows displays an extra warning when you try to run the executable. It’s pretty obvious that it would be ideal to test your signed drivers/executables on every different version of Windows you are targeting. To sign anything, you will need the Signtool.exe utility from Microsoft.
To obtain signtool.exe, I installed the latest version of the Windows SDK. You might need to download an appropriate cross-certificate in order to extend your chain of trust and meet all the desired signature requirements. All of the standard cross-certificates that go back to the Microsoft Code Verification Root are available for download from Microsoft. Your certificate provider might have some other useful cross-certificates available for download on their website.
Step-By-Step Uncomplicated Methods For Driver Support
A good option is the code signing certificate offered by Globalsign. You will have to choose whether to get an Extended Validation certificate or a normal certificate. The EV certificate is more expensive and probably more of a hassle, but it is required by Microsoft if you are going to sign kernel-mode drivers and you want those drivers to generally work on Windows 10. Also, an EV certificate will give you "immediate reputation with Microsoft SmartScreen", making it less likely for users to see random errors when they download signed executables from you. If your certificate uses SHA-2 or has SHA-2 certificates in its chain of trust, then you will not be able to use it to get kernel modules loaded into the Windows Vista 64-bit kernel.
On versions of Windows Vista without this update, when the end user double-clicks on a downloaded executable with a signature whose chain of trust uses SHA-2, nothing happens! Don’t use spaces in the INF file name.This is an additional requirement for driver package installation that was reported by Jimmy Kaz. I have not tested it myself, but he says that the driver package will appear to be unsigned in Windows 7 if the INF file has spaces in the name. WHQL The signature must come from the WHQL program. My understanding is that NVIDIA drivers you can submit your driver to Microsoft or some third party to be tested.
Thoughts On Necessary Factors For Driver Updater
To use a cross-certificate, you will have to include an argument of the form /ac "path-to-your-cross-cert.ct" when you invoke signtool. However, cross-certificates do not matter much anymore now that the Windows Hardware Developer Center Dashboard portal is available, which will sign drivers for you.
If your driver is OK, they will sign your driver and give you legal permission to use the Windows Logo to sell your product. WHQL is never actually required for your software or drivers to work and probably harder than just using a standard code signing certificate.
