The information requested by @Prométhée is really needed.

I am going to guess at the problem.

1 - windows 7 update -OR- a 3rd party update such as security, multimedia, or some app

Windows 7 support ended long ago.  It is possible that your system is attempting to obtain one or more modules from a Microsoft server and the items are no longer available.

 2 - You are updating to windows 10 which is still free

If your update is to go from 7 to 10 it takes a long time.  I assume you downloaded the "update now" 

button and not the ISO.
