Added in Windows 10, version 1709. This policy setting allows you to configure a default set of favorites, which will appear for employees. Employees cannot modify, sort, move, export or delete these provisioned favorites. Specify the URL which points to the file that has all the data for provisioning favorites (in html format). You can export a set of favorites from Edge and use that html file for provisioning user machines.

URL can be specified as:

  • HTTP location: "SiteList"="http://localhost:8080/URLs.html"
  • Local network: "SiteList"="\network\shares\URLs.html"
  • Local file: "SiteList"="file:///c:\Users\\Documents\URLs.html"

Important

Don't enable both this setting and the Keep favorites in sync between Internet Explorer and Microsoft Edge setting. Enabling both settings stops employees from syncing their favorites between Internet Explorer and Microsoft Edge.

If you disable or don't configure this setting, employees will see the favorites they set in the Hub and Favorites Bar.

Added in Windows 10, version 1703. Allows you configure the default search engine for your employees. By default, your employees can change the default search engine at any time. If you want to prevent your employees from changing the default search engine that you set, you can do so by configuring the AllowSearchEngineCustomization policy.

You must specify a link to the OpenSearch XML file that contains, at a minimum, the short name and the URL template (HTTPS) of the search engine. For more information about creating the OpenSearch XML file, see Search provider discovery. If you want your employees to use the Microsoft Edge factory settings for the default search engine for their market, set the string EDGEDEFAULT; otherwise, if you want your employees to use Bing as the default search engine, set the string EDGEBING.

If this setting is not configured, the default search engine is set to the one specified in App settings and can be changed by your employees. If this setting is disabled, the policy-set search engine will be removed, and, if it is the current default, the default will be set back to the factory Microsoft Edge search engine for the market.
