Windows 10 S, announced in 2017, is a “walled garden” version of Windows 10. It offers a faster, more secure experience by allowing users to only install software from the Windows App Store, and by requiring the use of the Microsoft Edge. Sometimes referred to as “Windows 10 in S mode,” Windows 10 S is installed on lower-cost laptops aimed at schools and students, including the Microsoft Surface Laptop.
Microsoft configured Windows 10 in S mode to run on lighter devices, provide better security, and enable easier management. The “S” doesn’t have a specific designation, but Microsoft generally surrounds it with words like security, streamlined for simplicity, superior performance, and whatnot. Windows 10 S stands out for these four different aspects of the operating system and its the Soul of Windows 10.
Windows 10 S is a special mode of Windows that substantially limits Windows 10 in a variety of ways to make it run faster, provide longer battery life, and be more secure and easier to manage. You can opt out of this Windows 10 S and revert to Windows 10 Home or Pro.
Functionally, Windows 10 S supports the same basic services as the underlying Windows 10 license. It simply targets schools in particular and wants educators to have the necessary tools for class management.
With Windows 10 S you get faster startup times and app activities. This is because there are no Windows legacy apps that slow things down. As long as you aren’t eating up too much RAM, Windows 10 S is positively snappy. Files automatically save in the cloud via OneDrive, which helps avoid bloat on smaller hard drives. Basic Windows features like Cortana, Windows Hello facial recognition, and Windows Ink for stylus use also remain.
