Give your mother/sister/kid/grandkid a call.
Go make a nice elaborate breakfast/lunch/supper/dinner.
Call that friend that you haven’t spoken with in months.
If you’ve got time to sit there and stare at the download bar, maybe vacuum the floor, or wash those windows.
The only person making a slow download frustrating is you yourself. Go do something in the mean while, come back in a couple of hours, and it might be done. If not? Maybe take a nice walk outside.
I don’t think my mother/sis/kid/grandkid are compatible with this title,
and I do not have enough free resources available to make breakfast/lunch/supper/dinner,
and I just get a 404 error when trying to call that friend,
and I have no free USB slots for the vacuum,
and as for washing windows, I did a full clean of Windows prior to commencing the update,
and I can’t go out due to Covid lockdown
