Microsoft announced today that it will make Windows 10 S available to developers and education customers. But sorry, Windows Insiders and other enthusiasts: It will not make Windows 10 S available for testing to consumers.

Windows 10 S should be live on MSDN by the time you read this. You will need a (paid, expensive) MSDN subscription to access this software.

“We’re releasing [Windows 10 S] today to developers because we want to be sure they are testing Windows 10 S,” a Microsoft statement notes. “We especially want EDU-focused developers to continue to innovate and make apps that teachers and students would use from the Windows Store.”

Next week, Microsoft will make Windows 10 S available to its Education customers alongside an Update Assistant tool. This will help these customers “make informed buying decisions regarding Windows 10 Pro EDU or Windows 10 S for their schools,” Microsoft says.

But it’s not for you. So Microsoft has not answered my call to open up Windows 10 S to Windows Insiders for external testing.

“This is very much meant only for developers and IT pros, not consumers to broadly download/switch to Windows 10 S,” Microsoft notes.

Maybe someday.
