well: made Macrium Reflect backup, did regedit.

Then as a test, ran Macrium Reflect which worked fine.

So looks ok

Thanks, wondering if anyone made a .reg file for others to download and apply yet, some others might not be so good when making changes in the registry. If someone hasn't yet, can they make one !

REG download now added to first post. :shawn:
I created my own, but maybe you could also add a delete reg as well, in case people get issues?

Of course, people should as a minimum backup the registry first, or make an image backup?

I created my own, but maybe you could also add a delete reg as well, in case people get issues?

Of course, people should as a minimum backup the registry first, or make an image backup?

Done. :shawn:

Would you set FeatureSettingsOverride to dword:00800008, if you also want to enable mitigation for Speculation Store Bypass globally? I seem to recall that the bitmap masks are additive. Thanks.

You'd need to add both below to enable the mitigation. If you like, the downloadable REG file in the first post will add them for you. :alien:

FeatureSettingsOverride DWORD to 00800000

FeatureSettingsOverrideMask DWORD to 00000003

FeatureSettingsOverrideMask DWORD to 00000003
If I use the value 00800000 for FeatureSettingsOverride, it disables global mitigation of Speculation Store Bypass. The previous value (8) enabled global mitigation of Speculation Store Bypass. That's why I wondered if you could add the values and use 00800008.

Not sure about that since those DWORDs are not there by default, and the article doesn't mention using any other values for them.
