msr.sys signed by Microsoft?

[HerveMat]

Hi,

I'm using the https://github.com/intel/pcm API to retrieve MSR (power) counters on an x86 architecture running Windows.
The problem is that the MSR.sys file generated or downloaded from https://ci.appveyor.com/project/opcm/pcm/build/artifacts is not signed by Microsoft.
On recent versions of Windows, the suggested solution of signing the driver locally fails. Is there a way to obtain an official driver signed by Microsoft?

Thanks in advance,
