Bigger problem is automatic installation of buggy patches!!!!
Scary part about Windows Server patching is when Microsoft issues a buggy patches that disables SQL server, Exchange server or causes BSODs! We have seen all of that lately causing widespread chaos for Systems Administrators. Always WAIT for patches to be one or two months old if possible before deploying. You do not want to volunteer to be a Microsoft Patch Beta Tester! Luckily Microsoft has a method to boot offline to a USB stick or CDROM now that lets you undo the bad patch on an unbootable system but still causes a lot of stress and headaches for sysadmins.
