McAfee VirusScan Enterprise (VSE) 8.8

Microsoft Windows 10 Anniversary Update


The Windows 10 Anniversary Update is not compatible with VSE 8.8 Patch 7 and earlier.

A block should be in place to prevent the Windows 10 Anniversary Update from installing when these versions of VSE are installed, but Windows 10 does not prevent this upgrade.

Performing this upgrade when VSE 8.8 Patch 7 or earlier is installed leads to system instability.


Microsoft did not emplace upgrade prevention protection when VSE 8.8 Patch 7 or prior is installed.


Microsoft is preparing a hotfix to Windows 10 that will prevent this upgrade. The release date for this hotfix is not yet known.
