I have had Win 7 for 6 years and performed updates without issue. I like to check and decide what I want instead of having windows install automatically or download and let me choose when to install.
Starting in June 26 I had problems. I would select updates for download and the screen would sit forever telling me it was downloading with 0% complete.
I checked around and found advice recommending I delete all folders under c:/windows/softwaredistribution. Problem was that windows would no longer have a record of the updates I have received and installed. This meant my computer would chug away for 2-3-4 hours while update confirmed the updates I was missing and re-building the data file.
I decided to do it and went ahead. You have to disable and then after deleting, re-enable the BIT service. Once complete my updates downloaded showing % complete and they installed - everything ok..
This week I tried to install 11 updates. Same problem - downloading 0% complete. I checked around again and found a Microsoft fixit tool that I could run and fix problems with update. I went ahead and did that but had to run it twice because in results the first time it said my service registration was missing or corrupt. This means your windows installation is not valid. The second time it was ok - ???
My software distribution data update file was wiped out so when I went back in to windows update it had to search and re-build the file. Another 4 hours.
While it was rebuilding I thought I would change my update setting to download but let me install them. I left my machine after it re-built the data catalogue of updates and did other things. Later I checked the Start button/Shut Down tab and guess what? There was the windows update icon. I went back into update to make sure what I had selected was what was going to be downloaded and then shut down the machine. All 11 updates were installed!!!!
What this tells now is that windows has recently disabled the ability to manually download selected updates. They want you to install them automatically or download automatically for later installation. BTW I always hide updates I don't want, especially some of the Optional. Also, I had previously rescinded my windows 10 invitation because I/we didn't like it after trying on my wife's computer and then restoring windows 7 which is not as easy to do as they say. Since then some of the updates were offers (you have to get more information to find that) for win 10 and on 2 occasions were re-install of GWX which had taken a lot of work to remove from dozens of places in my system. I even had to take ownership of registry files and change them. In restoring Task Manager it totally corrupted the schedules which took me another 2 hours to fix. MS has known about this issue since Aug 2015.
Anyhow, after July 29 I will take all the important updates without checking through them because the free win 10 offer will be gone.
What disturbs me is that Microsoft has obviously disabled the ability to manually download updates and I could find nothing from MS advising that . You have to let them do it. BTW I did all of the above on my wife's computer and the results were exactly the same. Start/Shut Down and the update icon was there.
