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.

Windows 2000

A watershed in Windows naming:
- first major Windows release since Windows 2.0 without a codename;
- first major Windows NT release whose workstation variant was named "Professional" instead of "Workstation";
- first major Windows NT release without the "NT" designation in the trade name, which caused confusion when Windows ME was released. The Windows line has been since dropped altogether, and Windows NT operating systems are now simply referred to as "Windows".
