This is not my own answer as I got this from Security Now transcript available on grc.com. Their answer is:
So that's the path in the registry, HKLM\Software\Policies\Microsoft\Windows\GWX. Under this GWX key you create a DWORD value named Disable, with capital D, lowercase "isable," so Disable, all caps GWX, and give that the value of one, and you are done. You have disabled Get Windows 10. And whatever Microsoft chooses to do, apparently they will honor that. It works today. We can hope it continues working.

Hope this helps.
3While this may answer the question, it would be a better answer if you could provide some explanation how to uninstall the update. – DavidPostill – 2015-08-06T20:48:58.400
