This feature in Windows NT 4.0 and Windows 2000, when activated will show you all the matching files and folders after typing the first couple of characters of a file or folder name, and then pressing a hot-key.

Ctrl-D Hot key for folders (directories) only
Ctrl-F Hot key to complete file and folder names

If you were to type cd my_d and then press Ctrl-D, all matching directories (like My_Documents) would appear.

To activate this feature for one session, at the prompt, type CMD /F:ON. To always activate this feature (and select your own hot-key) run regedit or regedit32 and go to key: HKEY_CURRENT_USER\Software\Microsoft\Commander Processor

Two DWORD values need to appear:

CompletionChar 0x4 (4=Ctrl-D, 4th letter)
PathCompletionChar 0x6 (6=Ctrl-F, 6th letter)

Use other digits for related Ctrl-letter combinations.

For a single user Windows NT 4.0 or Windows 2000 system, where you have the Administrator privileges, you can have the computer skip the bothersome Ctrl-Al-Del login step during the bootup process. Of course, this will allow anyone walking up to your computer to get into it, which may be desirable or not.
