How do I exactly add ssh to PATH on windows?

SSH.exe will be in C:\Program Files\Git\usr\bin

You need to locate the directory that ssh.exe is in.

You then need to go into System Properties (hit WINDOWS KEY+PAUSE), go to Advanced system settings, click Environment Variables...

Scroll down in the scrolling window at the bottom, until you see "Path" under "Variable". Click it, click Edit...

Go to the end of the value, add a semi-colon if one isn't there already, and type the path to the directory that ssh.exe is in.
