Windows 10 S Features Aug. 10th 2017 By J W Stuart
Windows 10 S is a limited version of Windows 10 that can only run apps or applications obtained from the Microsoft store.
The Microsoft Windows Store has a long list of Free, Paid and Trial software including games for Windows 10 S. Just remember if it’s not available from the store it will not run on 10 S.
If you don’t like the restrictions put on 10 S you can upgraded to Windows 10 Pro for a one-time fee of $49. It’s not apparent when this option will be available but apparently it is triggered when you try to install an application not available from the MS Store. Since this is an upgrade from 10 S to 10 Pro I strongly suggest you create an image backup of your “entire” disk drive before you start the upgrade.
