Different operating systems have different signal names to indicate that a segmentation fault has occurred. On Unix-like operating systems, a signal called SIGSEGV (abbreviated from segmentation violation) is sent to the offending process. On Microsoft Windows, the offending process receives a STATUS_ACCESS_VIOLATION exception.

A general protection fault (GPF) in the x86 instruction set architectures (ISAs) is a fault (a type of interrupt) initiated by ISA-defined protection mechanisms in response to an access violation caused by some running code, either in the kernel or a user program.
BSoDs in the Windows NT family initially used the 80×50 text mode with a 720×400 screen resolution, but changed to use the 640×480 screen resolution starting with Windows 2000 up to 7. Windows 2000 used its built-in kernel mode font, Windows XP, Vista, and 7 use the Lucida Console font, and Windows 8 and Windows Server 2012 used the Segoe UI ...
The MMU detects the page fault, but the operating system's kernel handles the exception by making the required page accessible in the physical memory or denying an illegal memory access. Valid page faults are common and necessary to increase the amount of memory available to programs in any operating system that uses virtual memory , such as ...
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 "blue screen of death" (BSoD) and allows the user to attempt to continue. The Windows DDK and the WinDbg documentation both have reference information about most bug checks. The WinDbg ...

When the MCEs are not fatal, they will also typically be copied to the system log and/or systemd journal. For some systems, ECC and other correctable errors may be reported through MCE facilities. [5] Example: CPU 0: Machine Check Exception: 0000000000000004 Bank 2: f200200000000863 Kernel panic: CPU context corrupt
