 Some things to try;

sfc /scannow

dism /online /cleanup-image /restorehealth

or possibly a repair install by running setup.exe from the root of the install media. I'm not a big fan of doing this and in my opinion time would be better spent standing up a new one, patch fully, migrate roles or applications over to it.

Windows showed the installation was successful and then asked for a restart. After restarting, it showed the update as failed.

I opened the Log folder but all I see are .etl files that are "garbled" when I open them in Notepad.

Appreciate all your help and guidance on this, as I know very little and am trying to learn as I go.

Do I need to do another process first, in order for the Get-WindowsUpdateLog to work?

Get this error:

Get-Process : A positional parameter cannot be found that accepts argument 'Get-WindowsUpdateLog'.
