Few days back, I did faced issues on Windows Server 2012 failing on Windows Update and put a post on my blog on it.
Further investigation made me to conclude that the issue is specific to one particular patch – KB2871690. While we select the entire updates, KB2871690 fails which revert the entire updates.
If we exclude this single update, the entire set of updates can get installed successfully in one stretch.
All went well with out KB2871690.
I even tried the standalone installer, but no luck.
Here is the error I see for stand alone installer.
This may be specific to my VM. But I did tested on a second fresh VM and was sucessfull on updates after excluding KB2871690.
I am checking this further and will update if I get some clue.
