I did have the SessionID wrong though, it is in the Administrator one. Sorry about that. Otherwise they are the same.

Now look at your PROPERTIES for the CMD prompt.

The START IN field on my machine has "%HOMEDRIVE%%HOMEPATH%" in it, which means C:\Users\Irv in my case. Do you have that entry? Even if you do, if you do not have those SET settings they are treated as nulls and you'd start in C:\ by default.

Not sure how this is actually created though?

There should be 2 ways to accomplish what you want. One would be a registry change that determines how to start CMD.EXE,

============
[HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor]
"AutoRun"="C: && cd \\
============

The other is to insert those SET variables via Control Panel -> System -> Advanced -> Environment Variables, and create HOMEDRIVE and HOMEPATH.
