I am trying to learn kernel driver development using the book Windows Kernel Programming. The first exercise is a simple do-nothing driver. I compile and create the solution successfully. I entered bcdedit /set testsigning on successfully. I disabled secure boot. The sc create command succeeded. When I enter sc start sample (sample is the name of the driver) I get error 1275, This driver has been blocked from loading. Any ideas
Windows 10, 64bit. 20H2 feature pack. I don't have a windows 7 machine so that is not an option.
