If you suddenly have a Program Files\rempl\remsh.exe, it is attempting to communicate with Microsoft servers. I’m still investigating what the shit it is, but it wasn’t present before so they must have snuck it into an update.
Looks like it initiated by the task scheduler. They added two new entries Microsoft\Windows\rempl shell and shell-unlock
I’d advise disabling these until info is released on what they do. As I said, I only caught it because my firewall alerted me to the attempt to talk to 188.8.131.52
