![]() Attach 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. 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. 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 during early driver development and for non-automated testing. ![]() ![]() By 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. ![]()
