I'm sorry, Mike, not sure that I can be of much help with Windows updates, I recommend you to troubleshoot it with suggestions from Microsoft (e.g. creating new admin user, resetting Windows Update components or resetting Windows completely). I had an issue with Windows Insider updates last year, fixed it using this set of commands (you need cmd with admin elevation):
net stop wuauserv
net stop cryptSvc
net stop bits
pause
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 catroot2.old
net start wuauserv
net start cryptSvc
net start bits
