Windows 10 in S mode is designed for security and performance, exclusively running apps from the Microsoft Store. If you want to install an app that isn’t available in the Microsoft Store, you’ll need to switch out of S mode. There’s no charge to switch out of S mode.
Switching out of S mode is one-way. If you make the switch, you won’t be able to go back to Windows 10 in S mode.
This tutorial will show you how to switch out of Windows 10 in S mode to the current Windows 10 Home, Windows 10 Pro, Windows 10 Enterprise, or Windows 10 Education edition for free.
