The Windows 10 Mail app shipped with Windows 10 when Microsoft launched the operating system in 2015, and its gentle new-mail chime became the default inbox alert on millions of PCs. Screen recorders, meme editors and streamers later lifted the tone for notification jokes, making it a softer cousin of the generic ding sound effect in short-form video. Since Windows 10 reached end of support in October 2025, the chime has doubled as a nostalgia cue — a tiny audio reminder of the mid-2010s desktop era.
