What can you do on Windows 10 that you can't do on Windows XP or Windows 7?

UPDATE:

It's highly instructive that, combined, after almost three hundred
contributions from over thirty authors, nobody can come up with even a
dozen important functionalities that we can do on Windows 10 that we can't
already do on all other Windows operating systems from Windows XP onward.
o *What can you do on Windows 10 that you can't do on Windows XP or Windows 7?*

Likewise, it's just as informative that we seem to arrive at a similar
conclusion for the various Microsoft Office versions extent:
o *What useful functionality is in the newer Microsoft Office*
*that isn't already in the older MSOffice 2007?*

The adult technical takeaway, could be, unless there's actually something
of truly useful value, that the updates are not as meaningful as Microsoft
marketing would have us attempt to believe.
