Strict Handle Checks = Speculative Store Bypass?

[ghost]

I just want to make sure that System Informer is reporting executable image mitigations correctly. When I enable "Strict Handle Checks" flag for an executable image, System Informer reports that "Strict Handle Checks" flag is enabled and "Speculative Store Bypass" flag is also enabled, but I never add "Speculative Store Bypass" flag to any images. In other words, I can't enable "Strict Handle Checks" flag for any executable image without "Speculative Store Bypass" flag being enabled along with it. They, for some reason, are enabled in pair. Images that natively support "Strict Handles Check" flag, such Shell Experience Host and Start Experience Host, do not include "Speculative Store Bypass" flag.

This is still very confusing...
