@mbk1969
Many thanks again for your very nice tool and your time to reply. My question was only to 'understand' and your tool is perfect for me 'as is'.

FYI: Here is GRC-InSpectre Release#5 run on a x99 PC "fully mitigate":

@mbk1969, thanks used your tool.




@100PIER, also used the cpumcupdate2.1 and install.bat using the latest Linux Processor Microcode Data File which told me "No CPU's needed update" in event viewer log, so used the uninstall.bat. (was not very surprising since no new microcode for IVB).

Thanks for the info about cpumcupdate tool. I"ll do tests to learn about it.
Here is a screenshot of the 4 tests Spectre/Meltdown tools run on X99, CPU Haswell-E µCode=3B, W10 RS3 64bit:


Specucheck Tool does suggest for CVE-2017-5754 mitigation apparently 2 differents options to get the "Kernel VA Shadowing Enabled" (yes case)).
I think I have used one (automatically ?, by default ?).
Who choose the option ? Is it W10 patch ?
What is the Option "with User pages marked Global" ?

@Fernando
I do recommend these tools to check the Spectre/Meltdown protection as well have the CPUID and µCode values used on a PC:
