Windows 2000 was released by Microsoft in 2000 as part of its Windows NT family, aimed at business desktops and servers. Its default sound scheme used short, professional alerts, and the notify chime became familiar to anyone who worked on those machines. As retro computing clips and meme edits spread on YouTube and TikTok, creators reused the sound to fake system messages, compare it to a modern ding sound effect, and signal instant nostalgia for early 2000s PCs, long after the operating system was retired.
