When installing a Windows Update, you receive an Error Code 80073712.
According to https://support.microsoft.com/en-us/kb/947821, 80073712 is ERROR_SXS_COMPONENT_STORE_CORRUPT The component store is in an inconsistent state.
From KB947821 I downloaded & ran the tool for my version of Windows. It can take a while.
When it was finished, I checked C:\Windows\Logs\CBS\CheckSUR.log. It found one error.
Doing a Bing search for part of the bad manifest, I was able to determine it was KB3150513. I manually downloaded the update from the Microsoft Update Catalog (http://catalog.update.microsoft.com/v7/site/Search.aspx?q=KB3150513) then installed it on the computer. No more error!
I didn’t have to do this but may have to also reset the Windows Update Components (https://support.microsoft.com/en-us/kb/971058)
