TAB Completion in DOS
This is for people who love doing stuff in the CLI (Command Line Interface).. Playing around with the . / TAB keys 
And what DOS misses is that wonderful command and directory completion feature available in linux shells. To enable TAB completion in DOS :
- Start Registry Editor with start -> run -> regedit
- Navigate to
HKEY_CURRENT_USER/Software/Microsoft/Command Processor - Find the CompletionChar property on the right and change its value from 0 to 9
Open up a command prompt and Give it a try
