A:Answer Switching out of S mode in Windows
Windows 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. Switching out of S mode is one-way. If you make the switch, you won't be able to go back to Windows in S mode. There's no charge to switch out of S mode.
1 On your PC running Windows in S mode, open Settings Gear-shaped Settings icon > Update & Security Circular arrows Sync icon > Activation.
2 In the Switch to Windows Home or Switch to Windows 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.)
3 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.
