If you want to fix your computer, please follow the steps in the tutorials, which I've condensed below. It's your computer and is your responsibility to fix it. We can gripe about Microsoft and their crappy support til we're blue in the face... it does nothing.
So, if you wish to fix your computer, please follow steps that have worked for every user that has tried them thus far.
Steps
- Repair install with Win 8.1 Installation media (run the installer from within Windows)
- Once the repair install completes and you sign back into windows, you'll need to activate Windows by going to PC Settings - Activate (It should automatically activate w/o the need for re-entry of activation key)
- Run dism /online /cleanup-image /startcomponentcleanup (this will take a while, do not cancel it or run Windows Update.
- Upon completion, restart
- Run dism /online /cleanup-image /restorehealth
- Upon completion, restart
- Run sfc /scannow
- Upon completion (without errors, unless the cbs.log details file permission access errors; if anything else, restart), run Windows Update and install the 46 updates
- Restart whenever Windows Update tells you to do so (You may have to restart quite a few times, depending if you get the 80070005 error [atleast I think that's the error #], which says that other installs are going on).
- After restart, run Windows Update again, all that should be available is the KB2919355 update package, totalling a little more than 800MB in size.
- Restart when Windows directs you to.
- Run Windows update again, make sure KB2919355 isn't still listed but in a smaller size, if it is, install (repeat until you receive no updates at this time).
EDIT:
If you don't have an 8.1 installation ISO, you will have to go to a software forum and download one that matches your version and architecture. Most users didn't bother using the save as ISO option within the 8.1 installer when they went from 8 to 8.1, which has lead to majority of users not having an 8.1 ISO to perform a repair install with. Repair Installs ARE NOT the same as Refresh/Rest (which shouldNEVERbe used). Repair installs can be explained in length by selecting the web link within my first tutorial for repair installs.
Secondly, and far more important, it's extremely irritating when a user comes to a forum, is given the exact instructions on how to fix their problem, then replies Microsoft [support staff] already did all that... Microsoft can't have tried a repair install on your computer, as it's impossible for them to stay connected to your computer while doing a repair install, and it's impossible for corruption to exist afterwards if the repair install and accompanied dism commands are executed properly.
