Problems are being reported with the MS16-072/KB 3163622patch. Admins are saying it breaks some Group Policy settings: drives appear on domain systems that should be hidden, mapping drives don’t work, and other typical GPO settings aren’t getting applied.
Although initial reports of misbehaving GPOs appeared for Windows 7 client PCs, it looks like the bug applies to Windows 7 clients, Windows 8.1, and even all versions of Windows 10 clients.
