[tex-live] install-tl-windows.bat unavailable in Microsoft Store

'ello friends,

This is the first time I hear of S-mode, so I decided to dig a bit. 
Found an Arstechnica quote that gave me shivers:

 > 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. Neither will the Windows Subsystem for Linux (WSL) that

 > the Store has no third-party command-line tools at all. To keep

Uh-oh.
