Windows 10 in S mode is designed for security and performance, exclusively running apps from the Microsoft Store. As you will be required to install software outside of the Microsoft Store, such as NAPLAN Locked Down Browser, Microsoft Office and Papercut Printers, you'll need to switch out of S mode.  

To switch out of S mode, please follow the below steps at home:

  1. Log in to your notebook and ensure that you are connected to your Home Wireless Network
  2. Open Settings  > Update & Security  > Activation.
  3. In the Switch to Windows 10 Home or Switch to Windows 10 Pro section, select Go to the Store. (If you also see an "Upgrade your edition of Windows" section, be careful not to click the "Go to the Store" link that appears there.)
  4. On the Switch out of S mode (or similar) page that appears in the Microsoft Store, select the Get button. After you see a confirmation message on the page, you'll be able to install apps from outside of the Microsoft Store.
