Adding some additional details. When trying DISM or SFC, the cursor blinks but nothing else happens. I cannot even type exit as it appears to be hung? I have to close the window. Additionally, when I check for updates, "checking for updates" runs continuously.
I looked at services, "Windows Modules Installer" and it was running. My default setting is manual? Rebooted and immediately went back to services and it is running. So I executed a STOP and then RUN and went back to try SFC and it ran as normal. DISM also acted normal. Ran sfc /scannow and DISM checks, no errors! Rebooted and checked the services and the windows modules installer was not running.
Checked for updates several minutes later and was greeted with 22621.2506 downloading. It install with no issue and the normal SFC and DISM commands worked as normal, no errors.
What "fixed" it not sure, but for now working fine. Tx for all the suggestions and help.
