Windows 10 S device specs

The Windows 10 S specifications are the same as the rest of Windows. We recently released a Windows 10 S installer that you can test on your existing devices so you will be able to test in your environment, plus try the experience on different devices and specifications. See here: https://docs.microsoft.com/en-us/education/windows/test-windows10s-for-edu. 

In terms of storage space when using our Set Up School PCs app devices can be optimized for shared usage, including better management of user profiles. Try using the shared device setting - 64 gb should work great in these scenarios.
