Following are only fixes on top of last Beta:


  1. XP BSOD as reported here
  2. We have tested v6420 against Meltdown patch released by Microsoft on 3rd Jan,2018 and there are no compatibility issues with either last production v6420 or this build. However as required by Microsoft that AV vendor should create registry key as defined in KB4056892, this version also creates required registry key.

While we provide updates next week. any user, who is currently using v6420 on Windows 10, can safely update to KB4056892 after creating key manually or can execute enclosed Enable_Jan2018_KB4056892_Patch.reg.txt file after removing “.txt” from end, that creates the required key.

Please share your valuable feedback.


Thanks Umesh. Much appreciated!

My machine has just updated and is working flawlessly as expected.

Windows 10 1709 (16299.192) x64

Windows 10 1709 (16299.192) x64 :-TU

Is the registry patch necessary for CIS 7.0 on Win7?


We have not seen patch for Windows 7 yet, but eventually it would and key would be needed.
So far we could see it released for version 1709 and have tested against that only.


I did a clean install after uninstalling 6464, then downloaded the MS Update from the Update Catalogue

Everything running well with no problems found.

KillSwitch installed with the Hosts file change (which works for that and the new ISE) but not for the CIS update for some reason!

Yes please.

PM me the crash dump link please.


I’m a little confused. Version 1709. What does this pertain to, CIS, Windows 7? Also, would it hurt anything to install the registry key on Win7 now?

Hi L.A.R. Grizzly,
That’s Windows Version pertaining to Windows 10 RS3.

We will be completing tests against Win 7 in next hrs and confirm.


Thanks. I’ll wait for the results!

Can you please break down what exactly this all means?
I’m having a hard time wrapping my head around what needs to be done here.
Are you saying that users of .6420 can go ahead now and update Windows 10 to KB4056892? However, prior to installing this Microsoft patch… we must first edit our registry manually and add the following key into our registry?

Key="HKEY_LOCAL_MACHINE"Subkey="SOFTWARE\Microsoft\Windows\CurrentVersion\QualityCompat" Value Name="cadca5fe-87d3-4b96-b7fb-a231484277cc" Type="REG_DWORD” Data="0x00000000”

I’m a little confused as to why the patch doesn’t just do this for us?

Hi Dustyn,
This planned release will set the key. In the mean time if you want, you can set key yourself as we don’t have any compatibility issues with last production version 6420.


Okay, I may try to apply the reg key manually. However, a user has reported a BSOD with .6420 after applying the update? Perhaps because he applied it to Windows 8.1? :;msg871059#msg871059

Hi Dustyn,
We are in the process of verifying patch against Win 7 and Win 8.
So far we could confirm on Win 10.

I will confirm.


Pls. see attachment.

Hi megaherz33,

When you say “Start”, do you mean Windows 10 Start Menu?
