`ssh` executable not found in any directories in the %PATH%

ERROR:

c:\Users\dhawal.vora>vagrant ssh
`ssh` executable not found in any directories in the %PATH% variable. Is an
SSH client installed? Try installing Cygwin, MinGW or Git, all of which
contain an SSH client. Or use your favorite SSH client with the following
authentication information shown below:

Host: 127.0.0.1
Port: 2222
Username: vagrant
Private key: c:/Users/dhawal.vora/.vagrant/machines/default/virtualbox/private_key

Kindly help????

Adding C:\Program Files\Git\usr\bin to the PATH environment variable.

Add it manually or I believe you could run this in cmd:

set PATH=%PATH%;C:\Program Files\Git\usr\bin

updated from @Ygor Thomaz's comments

or (64 bits)

set PATH=%PATH%;C:\Program Files\Git\usr\bin

If this doesn't fix your problem, go through :

Get SSH working on Vagrant/Windows/Git

You can alternatively install openssh from here and then you can add the ssh.exe to your PATH by:

set PATH=%PATH%;C:\Program Files (x86)\OpenSSH\bin

set PATH=%PATH%;C:\Program Files\OpenSSH\bin

With Windows 10 I also couldn't get the 'set PATH' option to work. But when I amended the PATH variable through System Settings and started a new command prompt it worked fine.

Also, putty worked perfectly after I read the screen which told me to use a username of 'core'.

'core' was a requirement of my configuration which was trying to launch CoreOS.

Adding C:\Program Files\Git\usr\bin to the PATH environment variable didn't work for me. So I configured PUTTY for ssh connection.

This well-written illustrative tutorial gives a great overview on ways to setup Vagrant SSH. The first way is via Git and the second way describes how to use Putty. It is very easy to follow.

Running Vagrant SSH on Windows

In my case even adding ssh to the PATH didn't solve the problem. What I had to do is connect to vagrant with ssh manually. After executing vagrant up, instead of executing vagrant ssh, I do this:
