For anyone who spends any amount of time dealing with Group Policy, you know it can turn into a maze of “Find the setting”. Was it under Computer Configuration\Administrative Templates\Windows Components or was it under Computer Configuration\Administrative Templates\System?
Never fear, some kind soul at Microsoft created http://gpsearch.azurewebsites.net/default.aspx. You can search for any string or text for find any GPO setting that matches. In addition it also has a great set of filters. Want to find all of the proxy settings that only apply to IE 9? Simply search for the setting you wish to manage and filter it to only include IE9.
As of the date of this post, it includes filters for Windows 10 as well as Microsoft Edge.
