A problem that has been going on for about a month, maybe longer. It started with an optional update, but seems to have turned into an important update. There are currently three updates that can’t be installed all the time, so I can’t be sure what it is anymore.

The main updates that continue to fail are Security Update for Windows 7 for x64-based systems (KB3063858) and Update for Windows 7 for x64-based systems (KB3068708).

The optional update that keeps failing is Internet Explorer 11 for Windows 7 for x-64-based systems, which is very confusing since I don’t even like or use Internet Explorer 11. It’s still a task when you see it hanging around the update area.
