A:Answer Thank you for the question. S mode is a version of Windows 10 or Windows 11 that's streamlined for security and performance, while providing a familiar Windows experience. To increase security, it allows only apps from the Microsoft Store, and requires Microsoft Edge for safe browsing. Apps and programs work the same as non-S Mode. You can switch out of S Mode (free, easy, not reversible) for the typical Home version of Windows, if you'd like.
