How to Change Foreground Flash Count for Windows 11 Taskbar Apps
You change the foreground flash count in Windows 11 to control how many times an app icon blinks on the taskbar when it needs your attention.
The foreground flash count is a Windows Registry setting that dictates the visual alert level for applications requesting focus. By default, Windows 11 flashes an app icon 7 times when it requires your interaction.
Adjusting this number, even to 0 for an indefinite flash, helps you tailor notification intensity to your preferences. This ensures you don’t miss critical alerts without being overwhelmed by constant blinking.
Edit the ForegroundFlashCount value in the Registry Editor. Open regedit, navigate to 🗝️HKEY_CURRENT_USER\Control Panel\Desktop, and change the DWORD value to your desired number of flashes. Restart your PC for the changes to take effect.

[DllImport("user32.dll")]
static extern bool FlashWindowEx(ref FLASHWINFO pwfi);

Changing the ForegroundFlashCount in Windows 11 lets you decide how often apps flash on your taskbar to get your attention, like setting it to zero for constant flashing.
Does changing ForegroundFlashCount require a system restart?
Yes, while some registry changes take effect immediately, modifying the ForegroundFlashCount usually requires a full system restart or signing out and back into your Windows user account to ensure the shell process correctly reloads the new parameter from the registry hive.
How do I disable taskbar flashing entirely in 🪟 Windows 11?
To disable taskbar flashing, you can set the ForegroundFlashCount value to 1 in the registry. Alternatively, you can modify the ForegroundLockTimeout to prevent windows from stealing focus, which often stops the associated taskbar notification behavior from triggering repeatedly.
