Tab Complete in Windows

Another one of those things that I can never remember off the top of my head so find myself constantly looking it up whenever I get access to a new machine.

I figure it may as well be my own site that I get the info from :-)

To switch on 'Tab Complete' in Windows command line change the following registry keys to '09':
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\CompletionChar
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\PathCompletionChar

or at the command line, type:
cmd /?
and read the help info, the second and third screens have this information as well. At least with XP Pro they do.

TweakUI from microsoft would have the graphical user interface for this.

This Microsoft feature was introduce by DOSKey in MS-DOS 4.0 (I believe). It was after Norton Utilities introduce such feature in their version 5.0 2 years earlier.

This feature was handy, but the slow floppy disk respond stop many users from using it.

I was using a lot of disk cache utilities at that time, and manage to by pass unnecessary disk reading by Norton Utilities.

Anyway, I don't know there is an registry setting either. Nice discovery, or research.

TweakUI is definitely the way to go, that along with many other 'hidden' fields!
