Microsoft released Windows XP in 2001 with a brief startup melody that became closely associated with the operating system. Its clean, welcoming notes were heard whenever many users logged into their computers, giving the sound lasting nostalgic value. Bass-boosted versions later circulated through meme edits and short videos, where distortion and stronger low frequencies made the restrained chime unexpectedly dramatic. It is often paired with retro computer imagery, system-error jokes, and the related Windows XP shutdown sound to evoke early-2000s desktop culture.
