Perform these steps using your development/signing computer. A driver package may contain sub directories like x86, AMD64, IA64, if the driver is built for more than one target processor type. Test Signing Procedureĭriver packages will contain the driver binary, the INF file, the CAT file and any other necessary files.
This computer must be running Windows Vista or later versions of Windows.

This is the computer that is used to install and test the test-signed driver package. This can also be the development computer. In order to use the driver signing tools, this computer must have the Windows Vista and later versions of the Windows Driver Kit (WDK) installed. This computer must be running Windows XP SP2 or later versions of Windows. This is the computer that is used to test-sign a driver package for Windows Vista and later versions of Windows.

Test signing and driver installation can be done on the development computer, but you may want to have two computers, one for development and signing, and the other for testing.Įxcerpt from How to Test-Sign a Driver Package: Signing computer Instead of using the above two methods to bypass driver signing enforcement requirements, the best approach is to test sign a driver package.
#Test windows 7 driver signature verification
See Appendix 1: Enforcing Kernel-Mode Signature Verification in Kernel Debugging Mode for how to accomplish this. However, be aware that there are also situations in which a developer might have to attach a kernel debugger, yet also need to maintain load-time signature enforcement. To open an elevated Command Prompt window, create a desktop shortcut to Cmd.exe, select and hold (or right-click) the shortcut, and select Run as administrator. To use BCDEdit, the user must be a member of the Administrators group on the system and run the command from an elevated command prompt. To use this debugging configuration, attach a debugging computer to a development or test computer, and enable kernel debugging on the development or test computer by running the following command: bcdedit -debug on This provision will allow installation of an unsigned driver for test purpose.Īttach a Kernel Debugger to Disable Signature VerificationĪttaching an active kernel debugger to a development or test computer disables load-time signature enforcement for kernel-mode drivers.
The following boot option screen will appear during reboot providing the option to disable the driver signature enforcement. This setting does not persist across system restarts. Windows Vista and later versions of Windows support the F8 Advanced Boot Option - "Disable Driver Signature Enforcement" - that disables load-time signature enforcement for a kernel-mode driver only for the current system session. This PnP driver installation behavior cannot be disabled on Windows Vista and later versions of Windows.
#Test windows 7 driver signature drivers
Signing the driver is required because Windows Vista and later versions of Windows display a driver signing dialog box for unsigned drivers that require a system administrator to authorize the installation of the driver, potentially preventing any user without the necessary privileges from installing the driver and using the device. However, to fully automate testing of a driver that is installed by Plug and Play (PnP), the catalog file of the driver must be signed. Developers can use one of the following mechanisms to temporarily disable load-time enforcement of a valid driver signature. However, this default behavior can be disabled to during early driver development and for non-automated testing. Installing an Unsigned Driver during Development and TestĮxcerpt from Installing an Unsigned Driver during Development and Test:īy default, 64-bit versions of Windows Vista and later versions of Windows will load a kernel-mode driver only if the kernel can verify the driver signature. However, eventually it will become necessary to test-sign your driver during its development, and ultimately release-sign your driver before publishing it to users. You can attach a kernel debugger to your test computer which will disable the same load-time enforcement checks after you use the correct BCDEdit commands. But this will become tedious after the first few uses. Initially you could use the F8 switch (on each boot, before Windows loads) to temporarily disable the load-time enforcement of requiring a valid signature in your driver.

Starting with Windows Vista, 圆4-based versions of Windows required all software running in kernel mode, including drivers, to be digitally signed in order to be loaded.
