working remotely on Windows via Remote Desktop if you’re hanging off GRPS or 3G connectivity somewhere in the mountains (for example) isn’t optimal. as I had to access some such servers remotely.

you can find cygwin useful (there’s also VanDyke V-Shell, a bit pricey and for non-commercial use). cygwin package installs UNIX environment, and that - yes - may include OpenSSH plus some tools (like scp for example)

you just need to download, and then run installation, selecting cygrunsrv and openssh. if you’re done - you just need to bootstrap SSH server and then start service responsible for SSH.

in Windows 7 you need to click on desktop with right button, select “Run as Administrator” and go through:

Copying skeleton files.
These files are for the user to personalise their cygwin experience.

They will never be overwritten nor automatically updated.

now just execute net start sshd or start Cygwin SSHD from Control Panel - and you can log in remotely using SSH or transfer files directly using SCP for example.
