Windows 10 S
But now comes a further indication that behind it could stand more, namely the complete end of Windows 10 p. Because a well-known and well-informed Microsoft Insider @h0x0d alias WalkingCat writes in a tweet that it seems that Windows 10 S is not an SKU (“Stock Keeping Unit”) or Edition more.
it looks like Windows 10 S is not a SKU/Edition anymore, any SKU/Edition of Windows can bu put "in S mode" 🤔

However, this does not necessarily mean that there is no longer a Windows 10 limited edition of Windows Store apps. According to WalkingCat, every Windows output can now be switched to an “S mode”. Such an outage for Windows 10 S would mean a symbolic step above all because the basic functionality of this operating system version would be preserved. Even now, the OS can pretend that you can install and run only apps from the store, which is usually safer, especially if the owner is inexperienced. Windows 10 S offers even more features or better said limitations, so Microsoft apparently wants to make a fixed part of all operating systems.
In fact, this means that you probably can not upgrade from Windows 10 S to Windows 10 Pro in the future, but will go the other way, if you want a “fenced” environment (such as for children).
