@winactive
Quick question: Do you have the two registry entries? And if yes with which values?
The reason I'm asking is because I have "Windows OS support for speculative store bypass didable is enabled system wide" to False. All the other values are the same as yours.

Yes
FeatureSettingsOverride DWORD 8
FeatureSettingsOverrideMask DWORD 3

; FeatureSettingsOverride values:
; 8 = Enable All (Speculative Store Bypass together with Spectre Variant 2 and Meltdown)
; 3 = Disable both Spectre Variant 2 and Meltdown
; 2 = Disable Meltdown (Kernel VA Shadow)
; 1 = Disable Spectre Variant 2 (Branch Target Injection)
; 0 = Enable Spectre Variant 2 and Meltdown
;
; FeatureSettingsOverrideMask value is always 3

Thanks a lot. For the possible values as well, which I already know... I wrote them hahahaha

Since I never installed any Microsoft OS updates (just using the hp BIOS/UEFI provided) I don't have the two Registry entries. I'll add them and run the PS script again to see what I get.
Thanks again man!!!

You need to reboot to get them to work. But yeah the variant 4 (Speculative Store Bypass) isn't enabled in OS by default so you do need the registry keys.

Guess what folks, they are doing it to us again....

Broadwell-E broken overclocking...same fixes as before

Taking ownership and replacing the file with an older version will put you into an unrecoverable boot loop. The easiest fix is to boot into a command window and delete the mcuGeniune_IntelUpdate.dll file in the system32 folder.
The only fix barring a BIOS update, is deleting the file.
