I need a modified driver (.sys) in order for my Intel wireless card to work. Of course, it won't load since the digital signature is not a thing anymore. Now, I've searched around for about a week but it seems like after build 1607 (or maybe earlier?) there is no way to disable the signature checking permanently (some posts in /r/Windows10 were informative) other than booting to startup options and pressing (F)7. Is there a better way to do it? Maybe I don't even need to disable it. Could I self-sign the .sys in some way and load it through test mode or something? I would appreciate the knowledge in here very much!
So essentially, there are several steps worth of hoops in which you must jump through in modern times to run unsigned kernel-mode drivers.
keep a eye on your system and see how stable does drivers are if windows begins to crash remove them immediately.
May I ask which modification and why you did it? Just curious (I work with hundreds of laptops with intel cards)
