I plan to reboot and rerun SFC one more time but please let me know what if any other tests you'd like to run to ensure all is well. I still have concerns about a few of the items I mentioned in my initial post from the Tweaking logs such as the missing Windows Update files (when I run the WU troubleshooter I continuously get "service registration missing or corrupt") and the permission issues, and paths missing in the Windows Store (I also continuously get "store is corrupt" messages when I run the troubleshooter.
Thanks for providing that fix and look forward to hearing back from you soon.:thumbsup2:
