Both updates is to make sure you upgrade asap

fyi, 16299 have these built-in, called WaaSMedic

 

There will be no CAB version of it or MSU?

 

It's not on catalog, so CAB only, if some-one takes the effort to fetch them.

For users with issues after updating the BIOS to mitigate Spectre v2.

Code:

::To enable Variant 2: CVE 2017-5715 "Branch Target Injection":

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverride /t REG_DWORD /d 0 /f

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverrideMask /t REG_DWORD /d 1 /f

::To disable Variant 2: CVE 2017-5715"Branch Target Injection":

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverride /t REG_DWORD /d 1 /f

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverrideMask /t REG_DWORD /d 1 /f

Note disabling and enabling the Variant 2 via registry setting changes will require a reboot and administrative rights.

Looks so:

 

It doesn't install anything, it should show up in the installed software list for uninstalling, but nothing gets installed, no messages, nothing.

 

Would assume it sets the reg entries i posted above on affected systems.

Yep. If you didn't install a BIOS update i'd recommend to set them to original values (FeatureSettingsOverride to 0 and FeatureSettingsOverrideMask to 3).

Since it seems to only set the entries, just change them manually to the defaults.

the value in FeatureSettingsOverrideMask set the mask and tell windows which bits is written in FeatureSettingsOverride
so you can request to set bit 1 or 2 or both which is 3 and more

 

I don't have these registry entries at all, is that OK?
Windows 1709 with KB4056892 & KB4058702 installed (and flash, of course).
