I reset an old Windows 8 system, I then downloaded all the Windows updates available. Only the Windows defender definitions failed to install but I tried again and they went in.
I then upgraded to Windows 8.1 using the store as it would not show up in Windows update. Anyway after it installed, I went into Windows update and clicked on "installed updates" and I noticed that one update comes up with nothing in the publisher name column. All the rest say Microsoft.
It is KB3063109. I've searched online to see if anyone else has had anything like this and I found nothing at all so I'm guessing this is unusual. Should I be concerned about this?
