Docker Quick start error: on Windows 10 - bash: docker command not found

Error:
Docker Quick start error: on Windows 10 - bash: docker command not found  

Issue:
Improper Docker installation on Windows
Git Bash / Git Shell couldn't find the Path for the Docker
Docker.exe is not set in the path.

FIX:

Give it a quick shot running Docker ToolBox.exe ( Actual docker install file for windows  which you have downloaded )

This will mostly fix the path and also the starting trouble with Docker Quick start shell window.
