Autocomplete for Windows Explorer

Have you ever noticed how some Windows machines have autocomplete in windows explorer and IE in the address bar while others just produce a drop down list?

To get autocompletion in the address bar add this setting:

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\AutoComplete]
"Append Completion"="Yes"

To get autocompletion in a DOS box by tyring the first few letters and pressing tab add this one:

[HKEY_CURRENT_USER\Software\Microsoft\Command Processor]
"CompletionChar"=9
