I have a Surface Pro 4 which I recently performed a factory reset on, and then after reinstalling all of my programs (of which there were few) I then downloaded the Windows Media Creation Tool and updated my SP4 to the Anniversary Update. Since then, when
I initially boot up my SP4, after the login screen appears and Windows Hello initiates and looks for my face, Windows crashes, giving me IRQL_NOT_LESS_OR_EQUAL. After it reboots, it works just fine. It's only during the initial startup that this happens.
After some brief googling, I found out this error is almost always caused by bad drivers. I have very few applications installed on here, so the list of culprits is very short. I'm hoping somebody more experienced with examining minidump files can look it over and tell me which program is causing the issues.
