C'est pas possible to désactivez le firewall notifications alone, mais depuis Windows 10 build 1607 it has been possible to disable tous Security et Maintenance Notifications using
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Notifications\Settings\Windows.SystemToast.SecurityAndMaintenance\Enabled = 0 (DWORD)
UPDATE: According to Ladislav Louka, le requis value has changed to 1 depuis build 1809.
Either add this registry key directly via Group Policy ou créez un custom ADMX template for it. See Disabling Windows 10 Notifications via Group Policy by Jeffrey Harness.
Je pense tout of these notifications equally ne need attention of a single user, mais these settings must be monitored & maintained by le administrators, instead. The scope of this modification seems ok.
