Hi millcoby,

I am Vijay, an Independent Advisor. I am here to work with you on this problem.

I recommend that you do a manual update for this KB.

1. Windows Key+X > Windows Powershell (Admin)

Type following (or copy and paste following) one by one and Enter

net stop wuauserv

net stop cryptSvc

net stop bits

net stop msiserver

Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

Ren C:\Windows\System32\catroot2 Catroot2.old

net start wuauserv

net start cryptSvc

net start bits

net start msiserver

2. Type following in Windows Start Search box (Cortana) and hit Enter %systemroot%\Logs\CBS > Rename CBS.Log to something else.

If it doesn't allow you to rename - Type services in Windows Start Search box > Click Services > Scroll down to find the Windows Modules Installer service and double-click on it > Set its startup type to Manual > Reboot your computer

Go to C:\Windows\Logs\CBS > Rename CBS.Log > Reboot your computer > Then go back into the Services App and set Windows Modules Installer Service back to Automatic Startup (Note CBS log files contain information about windows update, SFC etc)
