How to use alarms and timers in the Alarms & Clock app in Windows 10

Applies to: Windows 10

  • To launch the app, select Start  and select Alarms & Clock from the app list or type its name into the search box. 
  • Alarms and timers work even if the app is closed or your device is locked. If you see a warning that notifications only show if the device is awake, make sure your device doesn’t go to sleep (Go to Settings  > System > Power & sleep to adjust your device’s sleep settings). 
  • Keep your laptop or tablet plugged in and make sure the volume on your device is high enough to hear the alarm or timer.
  • To respond to an alarm, select Snooze, or Dismiss the alarm to stop it entirely.
