Command Prompt Options

Guide to Windows XP command prompt options. To enable or disable file and directory name completion on a computer or user logon session, run Regedit.exe and set the following REG_DWORD value: HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\CompletionChar\REG_DWORD To set the REG_DWORD value, use the hexadecimal value of a control character for a particular function (for example, 0×9 is TAB and 0×08 is BACKSPACE). User-specified settings take precedence over computer settings, and command-line options take precedence over registry settings.
