The Get Help app empowers customers to self-help with troubleshooters, instant answers, Microsoft support articles, and more, before contacting assisted support.
If you have a support app or support website you would like to direct customers towards, you can use unattend.xml to display your support option within the Get Help app. A link to your support app or website is surfaced wherever options to contact support are shown in the Get Help app. The first item in the list will be the link you provided.
Customers are sent to the Get Help from the Settings app, Cortana, Bing Instant Answers, the Start Menu, and numerous Microsoft web experiences. It is also possible to launch Get Help from your own apps and websites.
