Yes. Windows 11 includes alarms in the Clock app. You can set one from the Alarm section, and Microsoft says alarms continue when Clock is closed or the device is locked. The key limitation: the PC must be awake for the notification to appear, so do not rely on a Windows alarm to wake a sleeping computer.

Microsoft Support’s instructions list one preset alarm in the app by default. Its illustration shows a 10-minute snooze choice; that example does not establish that the interval is configurable or identical on every Windows 11 device. Microsoft’s Clock app instructions cover alarms and timers.
Will the alarm work if the app is closed or the PC is locked?
Yes. Microsoft Support states, “Alarms and timers work even if the app is closed or your device is locked.” Closing Clock or locking the screen does not by itself prevent the alarm from working.

Will a Windows 11 alarm go off while the computer is asleep?
Do not count on it. Microsoft warns that alarm notifications appear only while the device is awake. A locked screen is different from sleep: the former is supported in Microsoft’s guidance, while the latter can prevent the notification from appearing.
If the computer is going to sleep before the alarm time, review Start > Settings > System > Power & battery > Screen and sleep and adjust the sleep settings so the device remains awake. Microsoft also recommends keeping a laptop or tablet plugged in and setting the volume high enough to hear the alert. Whether you hear it still depends on your device’s audio setup.

What to check if the alarm time seems wrong

Timer
A timer counts down from a duration. Microsoft’s Clock instructions list four preset timers and an option to add another.
Focus
Focus sessions are a separate Clock productivity feature, not a way to create an alarm. A session can be started from Clock, Settings, or the taskbar calendar/notification area. You can choose a duration and whether to include breaks; Focus turns on Do Not Disturb by default and displays a focus timer. Its settings include duration, showing the timer in Clock, hiding taskbar badges or flashes, and enabling Do Not Disturb. Microsoft also documents optional Spotify audio and Microsoft To Do task-list integration for Focus sessions; neither is required for alarms or an alarm sound. See Microsoft’s Focus guidance.
