Windows 10 S mode only runs apps that you can find in the Microsoft Store. If you want to install an app that is not available in the Store, you will need to switch out of S mode.
NOTE: Switching out of S mode is one-way. You cannot enable it again once you go back to Windows 10 Home or 10 Pro.
- Click the Start , then go to Settings > Update & Security > Activation.
- In the Switch to Windows 10 Home/Pro section, click Go to the Store.
- On the Switch out of S mode page, click the Get button.
