While adding a AutoRun entry to HKEY_CURRENT_USER\Software\Microsoft\Command Processor like Shinnok's answer is the way to go it can also really mess things up, you really should try to detect a simple cmd.exe startup vs a script/program using cmd.exe as a child process:

IF /I x"%COMSPEC%"==x%CMDCMDLINE% (cd /D c:\)
