win8.1 error code 80073712 How to solve?

Win8.1update error code 80073712 Workaround:

Many users reflect a message that occurs when you install Win8.1 Update, cannot complete the upgrade, undo the changes, and then error code 80073712, as well as no details to tell the user how to fix the problem.

A user at the Microsoft Community Forum wrote: "The installation of KB2919355 was quickly completed at 74%, and at 89% it was very slow, and eventually there was an error message" The upgrade cannot be completed, the changes are undone, and no further details are available. I wasted a whole day trying so many times yesterday that it didn't help to use any of the methods mentioned in the previous post. I installed the Win8.1 on a 240GB SSD with 50GB of free space and the data stored on a separate drive.

While there are several solutions available, none of these options is very effective. Microsoft has not yet provided a solution to the problem, and foreign media has contacted Microsoft about the matter.
