Yes, I considered it. But my friend don't want to try to upgrade his
cygwin to new because he already tried it and after upgrade sshd was
unable to work. I also met this problem of unworkable sshd (the same
problem though another OS). After some experiments I realized that sshd
from new cygwin requires to grant 3 Local Policies to user under which
it runs. These policies are
Generate security audits
Replace process level token
Create process token
Without them new sshd doesn't work. My friend is not local
administrator, so he can't grant to himself this policies and can't
install new sshd.

So my question is: this disabling of accessing to desktop is also new
feature of new sshd? And can I allow him to access desktop somehow?
Or I have to install on my computer the old sshd to become sure that old
sshd will work on my OS too?
