So it looks like you have Delivery Optimization enabled. This basically means your computer is maintaining the various downloads for Windows updates and storing them locally for distribution to other computers on your network. You can turn this off by going to Start > Settings > Updates & security > Delivery optimization > turn off Allow downloads from other PCs.
Afterwards, clean up the Delivery cache: https://support.microsoft.com/en-us/help/404170...
