How to change Jenkins default folder on Windows?

Question

How to change Jenkins default folder on Windows where Jenkins runs as Windows service. I want to change C:\\Users\\Coola\\.jenkins folder to d:\\Jenkins<

Answer 1

I was able to change the JENKINS_HOME variable following this http://tech.nitoyon.com/en/blog/2014/02/25/jenkins-home-win/

Setting JUST %JENKINS_HOME% as windows system wide environment variable didn't have any effect!
