Windows 7 Updates Stuck.

Got the May batch of Windows Updates a day or two ago. Yesterday I tried to download and install all of the 14 updates, but the progress bar remained at zero. Earlier, I attempted to download and install the definition update just for Windows Defender, and that WAS successful. But once again, the rest of the .updates would not download and install. After a bit of online check, I found and ran the Windows Fix-It tool. The results of that were"

1)  Service registration is missing or corrupt.
2)  Windows update error 0X80070057(2016-5-12 T-05_30_45P
3)  A few lines of "problem fixed" without a description.

Go to Windows update screen to find scary red shield advising to update my computer. Under "most recent check" it says--->Never, with the same under "updates were installed--->Never. When I go to update history it shows that prior updates were downloaded and installed successfully, except for this last batch. So what I am getting now is just "checking for updates" endlessly.

Any ideas what I should  do next
