This clip comes from Windows 10 Build 10074, an early Insider Preview version of Microsoft's operating system released in 2015, when the new calendar and notification system was still taking shape. The short chime was designed to alert users to upcoming appointments without interrupting their work, a purpose reflected in its gentle tone. Today it survives mainly through soundboard archives and retro computing collections, where people save old system sounds that were replaced in later Windows releases. Its appeal lies in that brief window of Windows history, before the final version standardised its alerts.
About this sound
The calendar notification sound from Windows 10 Build 10074, a short soft chime for reminders and alerts. Perfect for retro tech videos and system sound edits.
This is the brief notification chime that accompanied calendar reminders in an early preview build of Windows 10, lasting just under three seconds. It opens with a gentle, rounded tone that rises slightly before settling into a clean, unobtrusive finish, more like a polite tap on the shoulder than a demanding alarm. Because it is familiar without being intrusive, it instantly signals a reminder, appointment, or scheduled event to listeners who grew up with Windows system sounds. In videos it adds a touch of everyday realism and quiet nostalgia, making a scene feel like a real desktop moment rather than a staged effect.
