Detecting installed SharePoint 2010 and 2013 version

I was looking for share point installed version on my VM and got the same questions from my developers. Here is the simple way to find the exact installed SharePoint version on your machine.
When Share Point is installed on your machine it marks the key in your registry. You can explore to the HKLM\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\14.0\WSS\InstalledProducts folder by opening REGEDIT window and check which key is placed there.

Following is the list of the registry keys and the specified share point versions.
