Works fine for me with a restricted admin account, so that's not a
generic problem.  The error you're referring to...

> [...]
>   178 1189861 [main] ssh-add 83428 __set_winsock_errno: connect:775 - winsock error 10036 -> errno 119

is not actually a problem but expected.  It's a simple EINPROGRESS which
is normal for a connect on non-blocking sockets.  Cygwin always switches
to non-blocking under the hood to allow to interrupt the process when in
a system call.

The actual error happens here:

> [...]

>    82 2191545 [main] ssh-add 83428 cygwin_getsockopt: 0 = getsockopt (3, 65535, 0x1007, 0x22C894, 0x22C898)
>    66 2191611 [main] ssh-add 83428 __set_errno: int cygwin_connect(int, const sockaddr*, socklen_t):806 val 111

The call to getsockopt is made by the connect procedure itself.  It's
unclear to me why you get a "connection refused" error (Winsock 10061 ==
WSAECONNREFUSED) at this point.  Is it possible that your firewall
software is blocking ssh-add?  Keep in mind that AF_LOCAL sockets are
not available on Windows natively and so are implemented as local
AF_INET sockets.
