Windows 10 How to Switch Out of S Mode
Windows 10 in S Mode is a more limited, locked-down Windows operating system. In S Mode, you can only install apps from the Store, and you can only browse the web with Microsoft Edge.
Microsoft is pitching security, speed, and stability here. Because Windows can only run apps from the Store, malware from the web won’t be able to run. You can’t install applications from the web, so they can’t install startup tasks that slow down your boot process or junkware that hides in the background and spies on you.
