This is one of those things that make many people say: "It borders insanity!" Fortunately, it doesn't happen frequently (thanks, Microsoft!) Last time it happened to me was yesterday and it repeated today with this insane type of error: WindowsUpdate_80073712.
I did also the DISM "torture" to no avail. This headache also coincides with the warning from the Homeland Security Department (USA) strongly advising people to NOT use Internet Explorer (versions 6 to 11). Maybe these two errors are related.
I honestly believe I give people a sane piece of advice: IGNORE THAT WINDOWS UPDATE THAT TRIGGERS THE WindowsUpdate_80073712 ERROR.
It didn't install for me yesterday and my PC worked perfectly. The update didn't install today and my PC works perfectly. I ignored Windows updates before and my PCs worked OK (XP, Win 7, Win 8).
The error I write about (80073712) occurred on my laptop, 64-bit Windows 8.1 Professional.
