Starting with the introduction of 10, I posted ( repeatedly ) for
anyone to give me one good reason to "upgrade" from 7 to 10. So far
nobody has been able to do that.

I have a few reasons to upgrade from Win7 to Win8.1. They apply to Win10 as
well.
On the other hand I see no reason to upgrade from Win8.1 to Win10.

The reasons to upgrade from Win7 to Win8.1 include:

* On Win8.1 one can use Classic theme with DWM enabled, on Win7 one cannot.

* A few bugs/glitches in the theme were fixed in Win8, such as a black pixel
on the
leftmost tab in tabbed dialogs and garbage on the window corner after
resizing.

* Quick start. Also the fact it keeps AMD Overdrive settings unlike full
reboot.

* Boot menu on the external monitor (I use laptop in the role of desktop,
with external monitor).

* Better hardware support, more universal printer drivers, newer driver
model,
USB 3.0 support out of the box.

* Seems working faster for me.

Win10 on the other hand, has tons of disadvantages compared to Win8.1.
