I'm not sure what advice to give.   Most of the systems I updated (at work) eventually found and successfully downloaded their updates... although it did take several hours for some to do so.   At home, something went awfully wrong, and I wound up manually downloading each of the updates.  I'd say to give the system another chance, especially since it found more updates waiting installation.   Maybe it would work out this time???
I will try to make this as clear as possible. I tried to download the available updates for my win 7 Premium 64bit. It just sat on "downloading" showing 0% after about 3 hours. When I went to shut down the computer, there was a symbol showing that it would install updates and then shutdown. I have never had that symbol before. When I next turned on the computer I got the configuring windows screen and then it opened normally. One update had been successfully installed. Being the fool that I am, I tried again to install the updates that are available. Same story - one more update installed. This has been going on for three days now. One update failed to install KB3172054 showed Code 80070013. It appears that it failed twice. This morning I went through the same deal with configuring windows and I am now totally unsure how to proceed. Obviously, updates are downloading - I just am not seeing it on the downloading screen. Would it be best for me to download the update repair tool from MS, or is there something else I should try to solve this problem with updates? I would really appreciate any advice you can offer.
