Hi, I'mCustomer Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP.
I'm sorry about the issue, Please se this link to speed up the windows updates : https://support.microsoft.com/en-us/kb/3102810
Please try resetting Windows Update, open https://support.microsoft.com/en-us/kb/971058 and download and save the Fixit from that page. When the download completes close all open applications and browsers.Now run the Fixit program and choose the Default mode.When the Fixit finishes running, reboot the computer and check to see if the system can update now.
Has everything worked out please?
