You can do it with a bit of preliminary fiddling.
1. Create a file called "cmddir.bat" in the root of C:
2. Edit this file to contain "cd <yourdefaultpath>".
3. Go to HKLM/Software/Microsoft/Command Processor in RegEdit.
4. Change the autorun value to the path of your batch file (c:\cmddir.bat in this case - you can call it what you want, and put it where you want).
Next time you go to command prompt, the batch file will be executed automatically (changing the path to the one in the batch file).
When you want to change the 'default' path in future, all you need to do is edit the batch file rather than messing about in the registry any more.
