Unlike test certificate, digital verified certificates have to be paid for. There is another workaround to load “unsigned” driver in Windows Vista and Windows 7, by signing the driver with a test certificate. User who feels that it’s troublesome to do so every time system is rebooting, it’s possible to download and install ReadyDriver Plus, which modifies Windows bootloader to automate the pressing of F8 and selection of “Disable Driver Signature Enforcement”. Easiest workaround to be able to load unsigned driver in Windows 7 or Windows Vista is by pressing F8 during system startup to display Advanced Boot Options, and select Disable Driver Signature Enforcement, on every boot up. User who needs to load unsigned driver is not out of options though. Previously in pre-SP1 Windows Vista, driver signature enforcement can be easily disabled with “bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS” command or “Ignore code signing for drivers” group policy, but the disable drivers integrity checks options no longer works after Microsoft released new kernel security update. The main purpose of the restriction is to enhance stability and reliability of Windows operating system by ensuring all device drivers passed Microsoft’s driver certification and compatibility test. The driver signature enforcement policy is implemented in both 32-bit (x86) and 64-bit (圆4) versions of Windows 7 and Windows Vista operating system, although it’s less strict in x86 OS, and in most cases, do allow unsigned drivers to load. Device driver software not successfully installed.A recent hardware or software change might be the cause. Please reinstall The Driver under Local system administrator account or try to start driver manually using “Low Level Driver Installation” shortcut. This driver has been blocked from loading.A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. Windows cannot verify the digital signature for the drivers required for this device. When an unsigned driver is installed, the device will be listed with an exclamation mark in Device Manager, and user may see the following error message: User who attemps to load an unsigned drivers will face the nonoperational device or malfunction device. Windows 7 or Vista will verify the digital signature of the drivers of each hardware devices before loading or starting the drivers. In Windows Vista or Windows 7 operating system, there is a strict driver signature enforcement policy of requiring Microsoft verified, certified and digitally signed device drivers to be installed.
