Narrator is a screen-reading app built into Windows 10.
Starting with Windows 10 build 17704, when Narrator launches, a new Quickstart tutorial experience will be available. The Narrator Quickstart will help you get up and running quickly with Narrator. It teaches the basics of using Narrator, such as learning the keys on your keyboard, navigation, the most used commands etc. At the end of the Quickstart there is a link to the User Guide where you can continue learning about Narrator.
Narrator QuickStart will show by default when the Heads up! Narrator keyboard changes message is closed.
When the Narrator Quickstart launches, Scan Mode may not reliably be on by default. Microsoft recommends going through the Quickstart with Scan Mode on. To verify that Scan Mode is on, press Caps Lock + Space.
This tutorial will show you how to turn on or off showing the Narrator QuickStart guide at the startup of Narrator for your account in Windows 10.
