How do I enable Tab to complete file names?

A. NT has this functionality built in, however by default it is disabled. To enable perform the following

1. Start the registry editor (regedit.exe)
2. Move to HKEY_CURRENT_USER\Software\Microsoft\Command Processor
3. Double click on the value CompletionChar
4. Make sure the base is Hexadecimal and then set the value to 9 and click OK
5. Close the registry editor
6. Start a new CMD.EXE session and the change will have taken effect
