How to Set an Alarm in Windows 10 | Windows Tutorial
For whatever reason, Windows didn't include alarms, timers, and stopwatches until Windows 8 rolled around. Windows 10 improves on those features, and this also basic function now works just like it does on almost every other operating system available. Alarms work just like you expect. You set a moment (and days) to the alarm to look off, pick a security sound, offer the alarm a label, and you’re off to the races.
