@showmethefacts, if you go to Control Panel/Windows Update and display 'View update history', which update(s) are failing? You can right-click in this window to copy the details.
80073712 is discussed at https://support.microsoft.com/kb/957310. if the sfc and dism commands do not resolve the problem, an in-place repair may be you best option but for that you will need the install media for your computer. Unfortunately, Microsoft does not allow you to download Windows 8.1 install media from http://windows.microsoft.com/en-US/windows-8/upgrade-product-key-only with a Windows 8 product key (you can get your key using http://www.nextofwindows.com/how-to-retrieve-windows-8-oem-product-key-from-bios/).
I do not have personal experience with using Windows 8 install media to repair a Windows 8.1 system, followed by applying all Windows 8 maintenance, then the Windows 8.1 upgrade and maintenance. Has anyone successfully done this?
http://www.howtogeek.com/186775/how-to-download-windows-7-8-and-8.1-installation-media-legally/ implies that you can create install media from your existing installation but since the Windows Update stack appears to be corrupted, I am not sure if the install media will be useful. Again, no personal experience.

There are Windows panels that do not support copy/paste. Windows 7+ has a Snipping Tool that can capture images and save them as a file or copy to the clipboard.
