Windows 10: Install Drivers Without Digitally Signed

Hi, I can't install a driver that I need because that isn't Digitally Signed. Help

:)

 

Getting "a digitally signed driver is required"

Hi Thomas,

This error can occur if there is a driver attempting to be installed on the system that was not signed by Microsoft digitally. Driver digital signatures help verify the integrity of the driver packages. To avoid this error, you need to disable the driver
signature enforcement. Follow the steps below:

• Press and hold the Shift key then click Restart button.
• Choose Troubleshoot, then select Advanced options.
  
• Select Startup Settings and click Restart.
  
• Once the computer restarts, you'll see a list of options. Press F7 to select
  Disable driver signature.
• Computer will now restart. Once done, check if the same error will occur.

Let us know the outcome so we can provide further assistance.

 

Digitally signed driver not verified by Windows

This is a typical error you get if vendors are still only cross-signing their drivers.

Note: Please provide your exact Windows Version next time!

However, I'm assuming that your Windows 10 version is at least 1607 (aka Redstone 1, Anniversary Update) and you have Secure Boot enabled.

If my assumption is true, this driver won't work.

I've extracted the .sys and .cat files from the installer package and verified that these drivers do not have a Microsoft signature:





Since Windows 10 version 1607, a tightened kernel driver certification is enforced. The new rule is that all Windows 10 drivers must be digitally signed by Microsoft, no more cross signing! Kernel driver developers must now use an Extended Validation (EV) code signing certificate and submit their drivers to the Windows Hardware Developer Center Dashboard Portal where the drivers will be signed by Microsoft.

In that case you would see a signature like this:

How do I allow cross-signed kernel drivers in Windows 10 version 1607 with secure boot enabled?

What are your options now?

• Ask the vendor to provide a Microsoft-signed driver (should be taken for granted actually)
  
• Disable driver verification (as you've already discovered)
  
• Disable Secure Boot

Wait, but have you done the whole step-by-step guide described in the OP? DDL/DTS isn't supported natively by Windows 8/8.1 either, unless if you do the steps listed there.
