ERROR_DRIVER_BLOCKED

Hi Everyone ,
while loading my first driver with OSR Driver Loader , error I got ->

“your driver is blocked from loading”

Error code is - 0x4fb

Did you enable test signing on the machine you want to run your driver? See

By default modern windows systems don’t allow loading unsigned or test
signed drivers or drivers which aren’t signed by a trusted authority - this
is for obvious security reasons.

I am using Windows 7 Home Premium 64 bit , from bcdedit command I have set the following -
nointegritychecks Yes
testsigning Yes

After setting this , windows is asking for digital signature for the driver . How to get certificate or
disable this security .

Google “Kernel Mode Code Signing Walkthrough”… this Windows Vista era document from Microsoft will walk you through the steps of how to test sign your driver and load it on Win7.

Thanks your very much sir !

Not enough. Hit F8 on each boot and say “Disable driver signature enforcement”
