There have been multiple tutorials posted multiple times with the exact steps needed to solve the corruption and get 2919355 installed. I've posted tutorials that work in all 6 threads dedicated to the 6 main errors experienced and in many I've posted the tutorials multiple times, and this isn't including the posts by others saying the same thing or offering the same steps to follow.
While this may be the first time many users [the average user] are experiencing anything like this, it only requires common sense to see the same worthless, cookie cutter responses from Microsoft do not solve anything and if followed, many will actually make things much worse (in other words, it doesn't take a genius to look at the posts by Microsoft employees in threads to see they're the same cookie cutter response over and over again, and then realize you should probably disregard all further mention of said responses/steps). I may know more than the average user, but I'm not an expert... just as many seeking a solution are not. What I see repeatedly though are people not only being told to a repair install and pretending like that was never even suggested, but are also being told by those of us who have done them that a repair install works, and still people ignore it (as you did in the previous thread for example).
All consumers should know, and if they didn't before, they got a rude awakening with this, that a device with a customizable OS comes with a use at your own risk and if something does screw up, you are the owner of said device and it is your responsibility to have personal responsibility for problems that occur with said devices and it is your responsibility to research solutions for said problems.
