Windows update

Hi,

This update:
Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB4019473).
Has been updating for a week and is still not done, is there anything i can do to speed this up?

Thanks

Sure, get a faster connection/system.

My connection is really really quick, do you know any other reason

What’s taking long ?? Downloading or installing ???
