As part of last month’s Patch Tuesday, Microsoft released a patch called MS16-072, a “security update for group policy.” The fix appeared in security patch KB 3163622, which is linked to numerous patches for Vista, Server 2008, Win7, Server 2008 R2, Win 8.1, RT 8.1, Server 2012 and Server 2012 R2. It was also part of Windows 10 cumulative update KB 3163018, for Win10 version 1511 build 10586.420 (in other words, Win10.1.13).
The patch caused problems, though — not with client-side computers, but in the way admins have set permissions for Group Policies — on the server side of the fence.
