The answer is really simple, you may have already it on your pc.
If you are looking for SSH probably you are a developer and you have installed git before. And the news is, GIT has ssh in their binaries.
Go to C:\Program Files\Git\usr\bin and check for ssh.exe or C:\Program Files\Git\usr\bin for old versions
And then add ” C:\Program Files\Git\usr\bin” to PATH at System variables. And now you can execute ssh commands with command line.
