You might see if going through the troubleshooting steps in the tutorial below may be able to help. I'm suspecting that option 14 may at issue here to clear the Store cache, so you might try that one first.
I found a solution. go to troubleshooting (press win+w >then type troubleshooting). now a window opens in desktop. click "fix problems with windows updates". now click next. windows will search for solutions, but it won't find anything. then windows will ask if you want to try in administrator mode. click yes. windows will find and solve the problem. that's it.
You're awesome! I tried absolutely everything/every suggestion, including the ones from Microsoft, and this was the only thing that worked! I will link back to your suggestion for all of the other people who had the same problem! Thank You!
