Microsoft announced the new Windows 10 S version.
Windows 10 S is streamlined for security and performance, and works exclusively with apps from the Windows Store, and uses Microsoft Edge as its default browser.
Windows 10 S integrates with OneDrive so files are saved to the cloud, in sync and accessible from your devices. Use compatible apps available from the Windows Store. If you need to use professional tools or would rather run non-Store apps, you can easily and affordably switch to Windows 10 Pro.
Your applications are delivered via the Windows Store ensuring Microsoft-verified security and integrity. Microsoft Edge is your default browser since it’s more secure than Chrome or Firefox. Windows Defender and all ongoing security features of Windows 10 are included.
