Blue Screen of Death
The user will only see the blue screen if the system is not configured to Automatically Restart (which became the default setting in Windows XP SP2). Otherwise, it appears as though the system simply rebooted (though a blue screen may be visible briefly).In Windows, bug checks are only supported by the Windows NT kernel. The corresponding system routine in Windows 9x, named SHELL_SYSMODAL_Message, does not halt the system like bug checks do. Instead, it displays the infamous BSoD (Blue Screen of Death) and allows the user to attempt to continue.
