I believe I don't use this to its full potential. But I use it to upload project web content to sourceforge.net, and for that OpenSSH works great!
It ruins the system path on Windows 7. After install only C:\Program Files (x86)\OpenSSH\bin is in system path.
This project worked very well for me, and installation went fine. ASIDE from the fact it deleted my path variables. I worked around this by system restoring, saving my path variables somewhere then undoing the restore. Finally appending openSSH's path to my path variables.
