Change method
To change the completion character in Windows 2000, use a registry editor. You can also change the value of this entry by using Command Processor (Cmd.exe), but only for the duration of that Cmd.exe's execution.

Note
CompletionChar and PathCompletionChar can appear in HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER. If both appear in the registry, the value of the entry in HKEY_CURRENT_USER takes precedence over the value in HKEY_LOCAL_MACHINE.
For the original release of Windows 2000, the default value for this entry is 0x20. For Service Pack 1, the default is 0x9.
Assigning the values 0x0, 0xD, or 0x20 to this entry disables file name completion rather than assigning a completion character.
The command-line switches take precedence over the registry settings while using Command Processor (Cmd.exe).

Tip
To enable or disable file name completion and directory name completion for one use of the command processor, at the command prompt, type CMD /F:ON (enable) or CMD /F:OFF (disable). This command sets the completion character to CTRL+F (0x6).
For more information about the file-name completion feature, at a command prompt, type CMD /?
