1. From Start menu click Settings and then open Update and Security.
2. Select Activation on the left and then click Go to Store.
3. In Switch out of S Mode page, click Get and then click Install. *
4. Finally click Yes, Lets go to switch out from S Mode.
* Note: If after clicking the ‘Install’ button you receive the error “Something happened and we couldn’t start the upgrade”, proceed and install all the available Windows 10 updates, restart your PC and try again.
4. When the installation is completed, you’ll be informed that you’ll be able to install apps from outside of the Microsoft Store.
