I know that this problem has been stated multiple times, but I cannot seem to find any solution. The issue is that I compiled in release mode the kmdf hello world example from Microsoft's website, but I am not able to run it. The reason is that when I try to launch the service, I get the following error: "The driver has been blocked from loading". I Obviously get this error because I have not signed the driver, but even though I have disabled signature enforcement on my updated Windows 10 machine (as stated here) I still cannot launch the driver, and I get exact the same message. So basically the option for temporarily deactivating signature enforcement, seems to serve a completely decorative purpose. So, is there any other way to launch my unsigned driver on my Windows 10 Virtual Machine, or I need to pay $100 to run my code on my own computer ?
The tutorial that you're using mentions that you need to provision your target machine for driver deployment, and leads to the "Provision a computer for driver deployment and testing" page which (among other things) has the following instructions:
On the target computer, run the WDK Test Target Setup MSI that matches the platform of the target computer. You can find the MSI in the Windows Driver Kit (WDK) installation directory under Remote.
Example: C:\Program Files (x86)\Windows Kits\10\Remote\x64\WDK Test Target Setup x64-x64_en-us.msi
If you want to deploy your driver manually (for example, if you're testing your driver on your development machine or in a VM), instead of running the aforementioned MSI you can manually enable test signing mode by running bcdedit -set TESTSIGNING ON from the elevated command prompt. You would need to reboot the machine for the changes to take effect.
See "The TESTSIGNING Boot Configuration Option" on MSDN for additional details.
