Windows 10 launched in 2015, and build 10240 was the release version first shipped to manufacturers and early users. Its system sounds were carried across most Windows 10 PCs, so the Notify Calendar chime became part of everyday desktop life for years. As tutorials, screen recordings, and nostalgic PC videos spread online, the short alert was saved separately from the system and shared as a standalone clip. It remains popular because it is instantly identifiable, cleanly recorded, and useful whenever a creator needs an authentic computer reminder sound.
About this sound
The Windows 10 Notify Calendar sound effect from build 10240, the short default notification chime people use for PC alerts and reminder jokes.
This is the short Notify Calendar notification sound from Windows 10 build 10240, the final release build of the operating system. It is a clean, soft digital chime with a gentle rising tone that lasts just a moment, designed to signal a calendar reminder without startling the user. Played out of context, it instantly feels familiar to anyone who used a Windows 10 PC, triggering that automatic urge to check a schedule or dismiss a popup. Creators use that instant recognition to add a realistic desktop feel or a small nostalgic punchline.
