Windows requires a digitally signed driver


Recommended Posts

Hello everyone,

 

I have been using Smart Defrag on all my devices for about two years now. Recently I built a new computer and I've only now thought getting Smart Defrag again. This time, after I install the Program, I recieve an error message which states "Windows requires a digitally signed driver". I do not know what causes this, if it changes anything or how to remove it.

I use Windows 10 Home 64bit and this is the first time I have ever encountered this problem.

This is the error I get. I got this picture from another website, since I could not use my original error message because it is in German.

 

Thank you in advance!

I hope that upgrading to latest version solved your problem with unsigned driver, but if not you can always install unsigned drivers, but only if you are 100% sure that driver file is not corrupted!!

 

You can find solid walk-through on this link https://en.code-bude.net/2015/08/19/how-to-install-unsigned-drivers-in-windows-10/

 

Hope that you find this helpful.
