Microsoft recently introduced a version of Windows called Windows 10 S, with the S standing for streamlined and secure. Unlike the Windows we are all used to, it only runs apps that are available from the Microsoft store. Presumably, the security of these apps has been vetted by Microsoft and they also run very efficiently.

Microsoft tried launching a similar version of Windows that only ran apps from the store 5 years ago called Windows RT. It was a huge failure. So why do it again?

The tech press has focused on Windows 10 S as being Microsoft’s answer to Google’s operating system called Chrome, which runs on a number of inexpensive laptops targeted at students.

There is certainly truth to that. However, it is likely that Windows 10 S is the version of Windows that Microsoft sees running on mobile devices. Cellular connected mobile devices. For example, a phone.

Microsoft does have something called Windows 10 Mobile currently for phones, but it is not clear where that is going. There is very little development happening on it. Microsoft has stopped making phones and its partners have pretty much stopped as well.

My guess is that Windows 10 S will be the version of Windows that runs on the next “phone” that Microsoft comes out with. Phone in quotes, because they have already said that they will not make a traditional smart phone like the iPhone or Galaxy. Microsoft is all about productivity, and while the device might be able to do voice calls, it will likely be more about getting work done.

Right now, most folks carry a phone along with a laptop or tablet and keyboard to actually do their work on.  With its Continuum feature, Microsoft tried to eliminate the laptop/tablet requirement but did not quite get there. But with a new mobile device running Windows 10 S and a keyboard, it just might make it.
