Shawn, if I have not had any problems since activating the mitigation, I can/should just leave well enough alone, and count myself lucky? Or should I go get this one?

I mean, if they are not sending it through Windows update, most non-geeks won't even know about this, so my takeaway is no need to get it...*Confused

:)

 

Windows freeze

If those other fixes don't work, try this:

https://support.microsoft.com/en-us/help/407813...

Check Update History to confirm you have KB 4078130 installed. Rather than uninstalling KB4054892, which fixed other problems as well as creating the reboot problem (and others), MS has created KB4078130 to fix the problems/

 

Random reboot without warning

2 weeks means it must be due to Spectre and Meltdown patch. See this for a relevance:

You need to install an update:

Hey Cliff, *Smile

Correct. This update is for those that have been impacted by the “higher than expected reboots and other unpredictable system behavior”.

If you're not having any issues, then you could skip this update if wanted.

 

Hi,
Wouldn't this be useless on win-10 seeing these are security updates and can't be disabled from reloading ?

 

Thanks for the info Shawn*Smile

 

I tried to install it earlier on , on a Intel Core i5 6300HQ (Skylake) system, but refuses to do so.

 

If your system seems ok it’s probably not worth trying to force it. Just wait for windows update to push the next one. I’m thinking of dusting off my Commodore 64 and going back to using that as my computer. A simpler time with no updates and no bios modifications and no threats!

 

Maybe it's because you didn't install the MCU from Intel in the first place. Understand that this KB is only for users who did and are having "higher than expected reboots and other unpredictable system behavior". Like in my case, I don't have to install this update to disable mitigation for anything, since so far I haven't got any microcode update from Intel. *Smile

 

Hi,

Not sure what you mean but see @IronZorg89 's posting just above this one.


Cheers, *Wink

 

I down loaded, right clicked, Run as Administrator, ask if I want to make changes and then I don't see anything.

It is not listed as installed. I guess if it is just making quick registry change it would be fast.

Any easy way to check?

 

Glad I didn't touch any of the microcookies from Intel then.

 

The update changes the "FeatureSettingsOverride" setting from 0 to 1.

Code: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management] "FeatureSettingsOverride"=dword:00000001 "FeatureSettingsOverrideMask"=dword:00000003 ; 3 = Disable both ; 2 = Disable meltdown (Kernel VA Shadow) ; 1 = Disable spectre (Branch Target Injection) ; 0 = Enable both ; ; FeatureSettingsOverrideMask is always 3[/quote]

 

Thanks. I just checked and both dwords are set to 1.
