have you tried the windows update troubleshooter?
search cortana for troubleshoot
choose control panel option
in next window, click view all in left menu
windows update troubleshooter should be towards bottom of list if sorted alphabetically
See if you can update to latest version of win 10 and bypass the updates?
Go to
this page and click the top link, it will download the upgrade assistant. run it and it will upgrade win 10 to Creators edition which was released on Tuesday
An alternate is to click 2nd link on same page, this will download the media creation tool, You can use it to update PC or maybe better choice, create a win 10 installer on USB. Advantage to USB is if the other two things fail, you need to download everything again. If USB fails, you just run it again.
If you get USB, you can run setup in file explorer and used it to update PC... or fresh install win 10 and ignore all the silliness with updates not working. but that might be a step too far.
