Answer 1

It looks as if your PATH environment variable is messed up by the installation of openport.io.

Echo still works because it is build-in into CMD.exe.
Curl isn't part of Windows and probably installed by openport.io and works because openport.io (i'm assuming) added its own folder to the PATH.

But it seems to have removed c:\windows\ and/or c:\windows\system32\ and/or c:\windows\system32\openshh\ from the PATH and you need those for standard Windows commands like WMIC and SSH.
