I've yet to see that message so here it's working. That doesn't help you but how did you get into this problem? Is there some device you don't have a signed driver for?
64-bit versions of Windows 10 and 8 include a “driver signature enforcement” feature. They'll only load drivers that have been signed by its manufacturer .. I bought and use Malwarebytes for my windows 10 and everytime every day program starts up I get the issue of this ( and other) programs needing digital assigned drivers for its compatibility issues with windows 10 ( I do not get this issue with my windows XP pro sp3 ) .. Malware bytes has assured me over and over that Microsoft has issued a fix for this but where is it? it was not in the anniversary update I have installed last August 2016.. Does anyone know about a fix for this issue???
