Developers can use one of the following mechanisms to temporarily disable load-time enforcement of a valid driver signature. 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. 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.
This PnP driver installation behavior cannot be disabled on Windows Vista and later versions of Windows. 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 setting does not persist across system restarts. Attaching an active kernel debugger to a development or test computer disables load-time signature enforcement for kernel-mode drivers.
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:. 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 open an elevated Command Prompt window, create a desktop shortcut to Cmd. However, there are situations in which a developer might need to have a kernel debugger attached, yet also need to maintain load-time signature enforcement. For example, when a driver stack has an unsigned driver such as a filter driver that fails to load it may invalidate the entire stack.
Because attaching a debugger allows the unsigned driver to load, the problem appears to vanish as soon as the debugger is attached.
Debugging this type of issue may be difficult. In order to facilitate debugging such issues, the kernel-mode code signing policy supports the following registry value:. The developer or tester can then choose to load the unsigned driver by entering g at the debugger prompt. Because of the access to the kernel, the drivers need to be signed officially. If the drivers you have got are not signed by Microsoft, they are not allowed to install on your computer. This is a protection move for your PC since you can clearly know some information on the software publisher, release time, etc.
This way can avoid malware attack to a certain degree. If you still need to install unofficial drivers, old drivers with no digital signature or unsigned drivers, you need to spend some time. How to install unsigned driver on Windows 10 in this way? Follow these methods given below now. This is a temporary way to let driver signature enforcement disabled. It will become enabled the next time you reboot Windows 10 unless you try this way again. The following are the instructions:.
Step 3: To install driver without digital signature, press F7 to choose the Disable driver signature enforcement option. Step 4: The system will boot to Windows and then you can install any driver that is not signed. After installation, you can restart Windows to let the option get enabled automatically. In Windows, there is a mode feature called Test Mode. If you enable it, driver signature enforcement will be turned off until you leave this mode. This is a permanent method and you can install unsigned drivers in Windows 10 easily in this mode.
