I'm assuming an up-to-date OS with all that implies, but no microcode update (most OEMs suck at this, especially for older systems). However, I hear Microsoft is going to use Google's Retpoline fix, so Windows machines may not require a microcode update after all?
So, assuming Microsoft applies all the necessary fixes on its side, will ReHIPS be able to contain even Meltdown/Spectre-vulnerable applications? I'm just trying to understand the level of protection ReHIPS offers in this situation.
