That's why you should always avoid complexity
The Windows 10 upgrade ads are just another bit of the needless complexity you get when using Windows, or increasingly systems designed by "Freedesktop/systemd" people.
That's why you should always try to cut down your systems as far as possible. Every feature you don't need is a potential bug, even though I'm sure Microsoft considers the Windows 10 ad screens an essential feature. It's just like the OpenSSL "keep alive" feature.
