The codename was the key to activating an easter egg in Windows 98:
- open the "Date and Time" control panel;
- go to the "Timezone" page;
- hold the Control key and drag a line with the mouse cursor from Memphis, Egypt (or maybe Cairo, codename of Windows NT 4 - the map is too small to tell) to Memphis, Tennessee. Still holding the Control key, drag another line from Memphis to Redmond, Washington;
- a window opens with the credits for Windows 98.
