You can go here and see how to manually enable Retpoline in Win10:
Mitigating Spectre variant 2 with Retpoline on Windows
I did this and the only change I see is I can no longer complete a PCMark10 benchmark. Could be related to this:

I notice Steve Gibson’s InSpectre negates Retpoline in Win10. I wonder which is better to use?
I don’t see where InSpectre does anything involving Retpoline?
Disable InSpectre performance good, BTIKernelRetpolineEnabled : False
BTIKernelImportOptimizationEnabled : False. Enable InSpectre performance bad. BTIKernelRetpolineEnabled : True
BTIKernelImportOptimizationEnabled : True
Admittedly I’ve got a touch of flu or something so I’m not thinking clearly but I’m not putting together what you are asking.
As far as I can tell, InSpectre hasn’t been updated with the new Retpoline info?
Thanks. I meant to say Performance slower if InSpectre release #8 enable protection then BTIKernelRetpolineEnabled : True
BTIKernelImportOptimizationEnabled : True
