Windüts XP

The name of a thing, and precisely what it represents, can change over time. For example, "windows" (the portals, not the operating system) as we know them today are a relatively recent version of an age-old hole in the wall.

For approximately 3,000 years, windows were known as "windüts." Subtly different than windows, "windüts " were wildly popular.

Cleopatra is credited with being the first to create the last stop before the modern window, opening/closing windüts (for use when it was hot), starting a trend still enjoyed 2,000 years later.
