Cmd.exe and the console window (as used by Cygwin) are separate
things. Windows automatically creates a console window when a console
program is invoked from Explorer. Cmd.exe is just one such console
program; Cygwin's bash.exe is another.

Paste by middle-click is enabled by default too.

It wasn't on by default originally, but it has been for a little while
now. Other ways include the Copy command in the right-click menu and
its Ctrl+Ins shortcut.

Note besides: Ctrl+Ins for copy and Shift+Ins for paste are standard
Windows shortcuts too. Ctrl+C and Ctrl+V can't reasonably be used as
shortcuts by a terminal because they're used by many terminal
applications. However, there's an option on the Keys page of mintty's
options dialog that allows Ctrl+Shift+C and Ctrl+Shift+V to be used

What sort of server is it?

Yep. Ye olde and ever-exciting ^? vs ^H issue.

Actually the Cygwin console's backspace character can be changed too,
but only through a control sequence:
For ^H: echo -ne '\e[?67h'
For ^?: echo -ne '\e[?67l'
Both the console and mintty use ^? by default. Linux terminals also
usually default to ^?, but BSDs might well default to ^H.

You could try the following command on the remote system to tell it
that the backspace key sends ^?:
stty erase '^?'
(Many ssh servers set that automatically in accordance with the
setting on the client side, but apparently some don't.)
