I'm Greg, an installation specialist and 8 year Windows MVP, here to help you.
There's a lot of turmoil with Windows Updates right now, with problematic Updates being withdrawn and updated while a half billion PC's are being rescanned constantly to sort them all out. So unless it's interfering with performance I'd give it a few weeks to sort itself out.
If it is interfering or you don't want to wait then there is a new guided walk-through from Microsoft for repairing Windows Update that leads up to resetting components if necessary:
https://support.microsoft.com/en-us/help/10164/.... Try running that first.
You can try installing Updates manually from Microsoft Update catalog by searching for them here:
http://www.catalog.update.microsoft.com/Search....
If Updates cause problems you can find out which one by checking at Settings > Update & Security > Windows Update > Installed Update History and uninstall them there.
You can block Windows Updates and Version Updates:

You can also install this tool to tell you exactly your level of protection needed for the CPU threat that has lately caused some disruption, how it may affect performance, and what you can do about it:

You can get more control over Windows Updates with some new features in the last two versions at Settings > Update & Security > Windows Update under Restart Options and set Active Hours when you don't' want to be bothered.
As a last resort, you can set a Metered Connection or disable Windows Update service and only install the Version Updates twice a year when you are ready via the most stable method - which isn't Windows Update anyway, but by running it from Media Creation Tool or the media it creates:

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
