Latest Windows update on CCE

Hi Experts,

 

One of our customer wants to patch Windows January 2018 and February 2018 updates on CCE according to the below article:

 

https://support.microsoft.com/en-us/help/4072699/january-3-2018-windows-security-updates-and-antivirus-software

 

However, the above article says the antivirus vendor needs to apply the below registry key:

 

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

 

Data="0x00000000”

 

Question:

 

Do we need to set this one on each Virtual machines for CCE (Both Sonus appliance and Windows 2012 standalone boxes)?

 

Any pointers would be of great help. Many thanks!!
