In my view, 8GB has been the minimum for several years for Windows 8 and 10.
I upgraded my middling Windows 10 PC (with reasonable SSD) several months ago from 8 to 16 and was surprised that it had quite such an impact. Much of the time my apparent memory usage is showing several gigabytes free but that upgrade made a very noticeable improvement.
I accept that there needs to be advertising but cannot see the value in forcing whack-a-mole on auto-opening videos.
