Enable tab auto complete in command prompt

Often I come across PC which does not have the "tab" auto complete enabled and it can be very frustrating to work with. Actually I just realized that Microsoft even has a KB to guide you through getting this fixed.

Enable "tab" autocomplete in (DOS) command prompt:

I figured its better for me to blog it here so that I can easily access this information when I need it.

1. Click Start, click Run, type regedit, and then click OK.
2. To enable automatic completion for the computer, locate and click theHKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor key.
3. To enable automatic completion for the current user, locate and click theHKEY_CURRENT_USER\Software\Microsoft\Command Processor key.
4. For folder name completion, double-click the CompletionChar value. Type in hexadecimal the control character that you want to use.
   
   For example, if you want to use the TAB key as the control character, the control character is 0x9 (type 9 as the value; Windows converts it to hexadecimal). If you want to use the same control characters that you use for a single command session, type 0x4 for CTRL+D and 0x6 for CTRL+F. You can use the same control character for both folder and file name completion.
5. For file name completion, double-click the PathCompletionChar value. Type in hexadecimal the control character that you want to use.
   
   For example, if you want to use the TAB key as the control character, the control character is 0x9 (type 9 as the value; Windows converts it to hexadecimal). If you want to use the same control characters that you use for a single command session, type 0x4 for CTRL+D and 0x6 for CTRL+F. You can use the same control character for both folder and file name completion.
6. Quit Registry Editor.
