How long did you let it run. Sometimes takes many hours to complete (many threads on issue) Try running SFCfix.exe by Niemero. Download it here, copy to desktop and run it. Post SFCfix.txt.
I just finished letting it run for 1 1/2 hrs. It came up with 49 updates to download. I started the download 20min ago. So far it hasn't downloaded anything yet. I will wait for the download to start. As soon as it either downloads and installs the updates or I give up I will run SFCfix.exe.
Giving up never solves problems. I'm assuming the (lag time) with the windows updates is due to the increased load windows 10 has placed upon M$ servers. Many have had similar issue. Let us know how it goes! :banghead:
