Configures the default New Tab page URL and prevents users from changing it.
The New Tab page is the page opened when new tabs are created (including the one opened in new windows).
This policy does not decide which pages are to be opened on start up. Those are controlled by the RestoreOnStartup policies. Yet this policy does affect the Home Page if that is set to open the New Tab page, as well as the startup page if that is set to open the New Tab page.
If the policy is not set or left empty the default new tab page is used.
This policy is available only on Windows instances that are joined to a Microsoft® Active Directory® domain. or Windows 10 Pro or Enterprise instances that enrolled for device management.
