Hoping that you can help with these errors. I've managed to get a number of the Windows updates installed after trying several things including sfc /scannow (multiple times over months), chkdsk, the utility to repair Windows Updates/Installers from Microsoft (which repair the ocx registrations, etc), but there are several updates that report reboot pending and some that just refuse to install. I can manually try installing them, but since there are so many missing, I wanted to try to make sure that they install in a stable environment. This PC is running Windows 8.1 and has had Windows Update problems since I got it brand new with Windows 8.0. There was a brief period of a few months where everything seemed to be working, then it stopped again. It's been scanned for viruses with mulitiple tools including McAfee Stinger, Kaspersky and a couple others and comes up clean. If you need any technical details, feel free to hit me up with anything - I'm a Windows admin.
