Managing and working with system drivers and the sensitive areas in which they reside is definitely not a job for the fainthearted since it requires advanced knowledge and understanding of how the operating system works, and how these resources and especially their modification may impact on the stability of your PC.
Microsoft's policy to allow only signed drivers to be loaded by the OS can be considered an extra safety measure that aims to make your system a bit more secure and prevent malicious code from execution.
However, there are some quite important drivers (especially those for graphics or audio) that must be loaded in order to have a hardware device function properly, but, since they are unsigned, the operating system refuses to load them.
To allow such components from trusted providers who, nevertheless, opted to leave out driver signing, you will need a dedicated utility that can make the whole registering process smoother. Such a tool is Driver Signature Enforcement Overrider, an application that can help you manage these sensitive files.
Since drivers need a certificate in order to be allowed to load and run on Windows, this program can help you create one. These certificates do not have to be digitally verified, but their existence is a must if a driver is to be accepted by Windows.
With Driver Signature Enforcement Overrider you can sign system files after enabling the 'Test Mode' from the main window. Unfortunately, you cannot add signatures to a batch of files, so each modification has to be done one file at a time.
In order to make the changes effective and have the newly signed drivers loaded by the operating system, you must reboot your computer. Also, it's very important to run the application with administrative privileges and have UAC (User Account Control) disabled prior to launching Driver Signature Enforcement Overrider.
Even if it may seem a risky procedure and in case you wish to revert the changes, this software allows you to disable the 'Test Mode' and have the drivers unloaded after a restart. Therefore, when handled with care, Driver Signature Enforcement Overrider can prove to be a valuable helper that can solve in an easy manner the unsigned drivers issues.
