WDK 8.0 samples fails to load drivers

    Question

  • I tried to run SIOCTL sample built as 32 bit debug on windows 8 x64 build 9200 system. It fails to load sample driver with error 1275 (ERROR_DRIVER_BLOCKED, This driver has been blocked from loading). Have just downloaded WDK sample and run with VS 2012.

    What I did wrong and what are possible workarounds?

    System boot have debug and testsigning set, selfsigned cert is in trusted root store. Debug cable was not connected.

  • It is very hard to get the signing right for the first N times.

    Connect the kernel debugger and try again.

  • use the deploy and debug built in option in VS2012. it will sign the driver, install the cert and install the driver for you.
