Windows product compatibility for McAfee products
Microsoft has requested security vendors to perform additional testing with their January 3 update, to ensure compatibility with that update.
Microsoft introduced a new registry key with this update to control if the update is available through the Windows Update service.
Automated mechanism to deploy the registry key update
Starting with the January 10 DAT (3221.0) updates for Endpoint Security (ENS) 10.0.2 and later, the registry key will be automatically updated for customers.
NOTE: Safety Pulse, which is enabled by default, must be enabled to download ENS DAT 3221.0.
Starting with the January 12 DAT (8772), customers who use VirusScan Enterprise (VSE) 8.8 and receive DAT updates will have the registry key automatically updated.
The DAT adds the check for the registry key, and sets it if it is not present. Customers who have already set a registry key will not have any issues.
For customers using ENS 10.0.1 or earlier, see
KB90180 - How to deploy the required registry key via automated executable.
NOTE: Microsoft no longer performs AV compatibility checks for supported Windows 10, 8.1, and 7 SP 1 devices. But, McAfee will continue to set this registry key to ensure compatibility for other devices. For more information, see the following Microsoft article:
Important: Windows security updates and antivirus software.
Manual methods to deploy the registry key update
To receive patches through Windows Update, customers are advised to create the following new registry key:
RegKey="HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\QualityCompat"
Value Name ="cadca5fe-87d3-4b96-b7fb-a231484277cc"
Type="REG_DWORD"
Data="0x00000000"
In environments with Active Directory, this key can be deployed through GPO. Instructions on how to deploy through GPO are available at:
https://technet.microsoft.com/en-us/library/cc753092%28v=ws.11%29.aspx
Customers who are not using Windows Update can directly download and apply the Windows Update from the Windows Update Catalog at:
support.microsoft.com/en-us/help/323166/how-to-download-updates-that-include-drivers-and-hotfixes-from-the-win.
NOTE: When you download Windows updates, Windows 7 operating systems must be updated to SP1 to pull updates from Microsoft Windows Update.
