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 whether or not the update will be available via the Windows Update service.
Automated Mechanism to Deploy the Registry Key Update
Starting with the January 10th 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 (enabled by default) must be enabled to download ENS DAT 3221.0.
Starting with the January 12th 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 should 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. However, 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 via 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 via GPO. Instructions on how to deploy via 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 downloading Windows updates, Windows 7 operating systems should be updated to SP1 for pulling updates from Microsoft Windows Update.
The following products have been tested and are confirmed as compatible:
Testing is ongoing for all McAfee products and no compatibility issues with the Microsoft update have been found so far. We expect testing to be complete on our endpoint products soon, and will update this article when we have a new estimated completion date.
