Windows 10 often downloads a large volume of updates. This is not a problem when you have good connectivity. When you’re on some slower network like ADSL it might lead into problems with connectivity.
One option how to limit the amount of downloaded data by Windows 10 update is to set a connection as Metered connection.
Search for Change Wi-Fi settings in start menu:
In Wi-Fi section scroll down below list of available networks and click Advanced options.
Flip the toggle Set as metered connection to On.
Windows will limit the amount of downloaded data and it will download only necessary stuff.
