Windows 10 S: no command line apps, free Pro upgrades for assistive tech users

First, a thing 10 S won't do: run command-line applications. CMD and PowerShell, the two built-in Windows command-line interfaces, won't be supported.

The rationale is that the built-in command-line applications include dangerous tools (for example, the diskpart partitioning program) that can break things, and the Store has no third-party command-line tools at all. To keep Windows 10 S protected against user error, they're all prohibited.
