The Opt-in Wizard displays the first time users run a 2013 Microsoft Office application, which allows them to opt into Internet-based services that will help improve their Office experience, such as Microsoft Update, the Customer Experience Improvement Program, Office Diagnostics, and Online Help. If an organization has policies that govern the use of such external resources, allowing users to opt in to these services might cause them to violate the policies.
Set the policy value for User Configuration -> Administrative Templates -> Microsoft Office 2013 -> Privacy -> Trust Center 'Disable Opt-in Wizard on first run' to 'Enabled'.
