While most drivers comes from the system or is supplied with the digital signature, there is also a group representing drivers not having digital signatures.
This group may include drivers very unusualor specialized equipment, hardware drivers , and the old and incompatible home made drivers.In Windows 7 64 - bit Edition driver signing policy displays a warning message when you attempt to install this type of drivers is controlled via popup with prompt of acceptance that we are installing the unsigned driver. Unfortunately, Windows 8 64 - bit Edition is with bare differently and unsigned drivers are completely blocked.
Of course, as in the majority of cases there is a way to get around this type of tightening. The easiest way to achieve this might be to use the command line and several commands:
- while in the desktop Modern UI start typing CMD and when you get in the right ribbon CMD, right mouse click then select run as administrator
- at the command prompt, enter "bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS " and hit enter
- Now we write command "bcdedit -set TESTSIGNING ON"
- at the end of " hutdown- r"
And after the reboot we can install the drivers thah are not digitally signed. Of course, leaving the status quo may be the way to serious security vulnerabilities , so anyone who has already done what he had to do is advised to return to the status before the change. Just in the CMD window, enter the following commands:
- "bcdedit -set loadoptions ENABLE_INTEGRITY_CHECKS "
- "bcdedit -set TESTSIGNING OFF"
