rempl/remsh.exe running from October 2017 update

Anyone knows what this does or is supposed to do? Perhaps to prepare or allow the Fall CU to take place?

My search engine, ecosia, and my browser, pale moon, did not arrive at any info, other than that it is fairly new(?). (I had just gotten around to updating the OS, 1607, with the October kb.)

Came across a hint or a clue as to what remsh.exe may be or do.

When I ran Autoruns, it had two entries for remsh.exe: shell and shell-unlock.

Although the publisher for remsh.exe is Microsoft, it is baffling why it was not installed and embedded amongst all the other Microsoft 'bloatware'. Instead, it had its own folder, rempl (lowercase), directly in Program Files.
