One problem i have encountered during HLK testing, is that when i disable driver signature enforcement during HLK testing and set the testsigning on (because obviously i have not received the Microsoft digital certificate to load and install drivers normally), after reboot which is required by some tests, the signature enforcement comes back on.
Note that i have disabled DSE by holding shift during shutdown and pressing 7 during boot.
My questions are:
Shouldn't i do the tests with a driver that is not signed? Because i think if i do a self sign it might solve the problem, but wouldn't Microsoft just append its signature after my self signed cert in that case? What is the official way of doing the tests?
How is my test passing after reboot when my driver is not even loaded?! For example the Hyper-V test seems to require a reboot even tho it states it doesn't, and the funny thing is that after the reboot, even tho my driver is not even loaded anymore, i pass the tests! This doesn't even make any sense?
