Never miss an alert where sound isn't an option
Working somewhere sound has to stay off β a library, a shared office, a meeting room β this feature flashes your screen the instant an error or notification sound would normally play, so you don't miss anything important.
Pair it with a quieter overall setup
If you're tuning your PC for quiet environments, it's also worth checking whether background apps can be muted individually in the volume mixer, so only the alerts you actually care about ever make noise β or a flash β in the first place.
Frequently Asked Questions
The screen flash is too distracting β what can I do?
Narrow the flash scope from the whole screen to just the active window's title bar; it's far less distracting while still catching your attention.
Does this setting apply to every sound?
It applies to system sounds and notification chimes Windows itself plays, not to sound you deliberately play yourself, like music or video.
