Automate GPO settings

Hello All,
I want to automate a task in Windows server 2008 R2 where we need to “Turnoff Event Shutdown Tracker”. This can be found in the path Gpedit.msc – >Computer Configuration ->Administrative Templates ->System -> Display Shutdown Event Tracker – Disable. I tried to change registry keys but it did not work for me. Any solution directing me to accomplish the task at the earliest would be appreciable.
