The Blue Screen of Death (BSoD), officially known as a Stop error, Blue screen error, fatal error, or bugcheck[1][2][3] is an error screen displayed by the Microsoft Windows or ReactOS operating systems.

The screen shows in the event of a fatal system error and indicates a system crash, system termination, or system failure. It indicates that the operating system has reached a critical condition where it can no longer operate safely. Possible causes of a Blue Screen of Death include hardware failure, an issue with a device driver, or an unexpected termination of a crucial process or thread.

Contrary to popular belief, the Windows Embedded Compact (formerly known as Windows CE) line do not contain a Blue Screen of Death screen.[4]

video icon Windows 1.01 Blue Screen of Death: Long version, showing installation of MS-DOS 6 and Windows 1.01, and the failed startup of Windows 1.01.

An early blue error screen first existed in the Beta Release of

Windows 1.0; if Windows found a different DOS version than it expected, the error message "Incorrect DOS version" alongside other text messages detailing what check failed to pass would be appended to the boot screen before starting normally.[5] In the final release (version 1.01), however, this screen prints out random characters after the "Incorrect DOS version" text as a result of a bug in the Windows logo code.[5]
This is not a crash screen, however; upon crashing, Windows 1.0 either locks up or exits to DOS.

Windows 3.1 changed the color of this screen from black to blue. Windows 3.1 also displays a blue screen when the user presses the Ctrl+Alt+Delete
key combination while no programs were unresponsive (the reverse is true for when there are unresponsive programs). As with prior versions, Windows 3.x exits to DOS if an error condition is severe enough.

The original Blue Screen of Death from Windows NT 3.51 (Italian
localization).

The first Blue Screen of Death appeared in

all Windows operating systems
released afterwards. In its first iteration, the error screens started with *** STOP:, hence it became known as a "stop error."

BSoDs can be caused by poorly written device drivers or malfunctioning hardware,[7] such as faulty memory, power supply issues, overheating of components, or hardware running beyond its specification limits. In the Windows 9x operating systems, incompatible DLLs or bugs in the operating system kernel could also cause BSoDs.[8] Because of the instability and lack of memory protection in Windows 9x OSes, BSoDs were much more common.

Incorrect attribution

On September 4, 2014, several online journals, including

Raymond Chen, entitled "Who wrote the text for the Ctrl+Alt+Del dialog in Windows 3.1?".[19] The article focused on the creation of the first rudimentary task manager in Windows 3.x, which shared visual similarities with a BSoD.[19] In a follow-up on September 9, 2014, Raymond Chen complained about this widespread mistake, claimed responsibility for revising the BSoD in Windows 95 and panned BGR.com for having "entirely fabricated a scenario and posited it as real".[20] Engadget later updated its article to correct the mistake.[11]

In the

kernel mode encounters an error from which it cannot recover. This is usually caused by an illegal operation being performed. The only safe action the operating system can take in this situation is to restart the computer
. As a result, data may be lost, as users are not given an opportunity to save it.

The text on the error screen contains the code of the error and its symbolic name (e.g. "0x0000001E, KMODE_EXCEPTION_NOT_HANDLED") along with four error-dependent values in parentheses that are there to help software engineers fix the problem that occurred. Depending on the error code, it may display the address where the problem occurred, along with the driver which is loaded at that address. Under Windows NT, the second and third sections of the screen may contain information on all loaded drivers and a stack dump, respectively. The driver information is in three columns; the first lists the base address of the driver, the second lists the driver's creation date (as a

RAM). The resulting memory dump file may be debugged later, using a kernel debugger. For Windows, WinDBG or KD debuggers from Debugging Tools for Windows are used.[28] A debugger is necessary to obtain a stack trace, and may be required to ascertain the true cause of the problem; as the information on-screen is limited and thus possibly misleading, it may hide the true source of the error. By default, Windows XP is configured to save only a 64kB minidump when it encounters a stop error, and to then automatically reboot the computer. Because this process happens very quickly, the blue screen may be seen only for an instant or not at all. Users have sometimes noted this as a random reboot
rather than a traditional stop error, and are only aware of an issue after Windows reboots and displays a notification that it has recovered from a serious error. This happens only when the computer has a function called "Auto Restart" enabled, which can be disabled in the Control Panel which in turn shows the stop error.

Microsoft Windows can also be configured to send live debugging information to a kernel debugger running on a separate computer. If a stop error is encountered while a live kernel debugger is attached to the system, Windows will halt execution and cause the debugger to break in, rather than displaying the BSoD. The debugger can then be used to examine the contents of memory and determine the source of the problem.

A BSoD can also be caused by a critical boot loader error, where the operating system is unable to access the boot partition due to incorrect storage drivers, a damaged file system or similar problems. The error code in this situation is STOP 0x0000007B (INACCESSIBLE_BOOT_DEVICE).[29] In such cases, there is no memory dump saved. Since the system is unable to boot from the hard drive in this situation, correction of the problem often requires using the repair tools found on the Windows installation disc.

Details

Japanese Language), Note that the sad emoticon
is not present.

Before Windows Server 2012, each BSoD displayed an error name in uppercase (e.g. APC_INDEX_MISMATCH), a hexadecimal error number (e.g. 0x00000001) and four parameters. The last two are shown together in the following format:[30]

error code (parameter 1, parameter 2, parameter 3, parameter 4) error name

Depending on the error number and its nature, all, some, or even none of the parameters contain data pertaining to what went wrong, and/or where it happened. In addition, the error screens showed four paragraphs of general explanation and advice and may have included other technical data such the file name of the culprit and memory addresses.

With the release of Windows Server 2012, the BSoD was changed, removing all of the above in favor of the error name and a concise description. Windows 8 also added a sad-emoticon as well (except on the Japanese versions

memory dumps. Since Windows 10 version 1607, the screen features a QR code
for quick troubleshooting. Windows 10 versions 2004–22H2 and Windows 11 changed the text slightly from "Your PC ran into a problem" to "Your device ran into a problem".

Windows 9x

See also: Windows 9x

Windows 9x is a community nickname given for Microsoft's line of consumer-oriented operating systems released from 1995 to 2000. The series includes Windows 95, 98, and Me (although the latter OS does not match the naming scheme of the two prior OSes). All Windows 9x operating systems are based on the Windows 95 kernel and MS-DOS, with the MS-DOS portion running versions 7 and 8.

Blue Screen of Death

The Blue Screen of Death in Windows 9x, as it appears on Windows Me
.

The Windows 9x operating systems used the Blue Screen of Death as the main way for virtual device drivers to report errors to the user. This version of the BSoD, internally referred to as "_VWIN32_FaultPopup", gives the user the option either to restart the computer or to continue using Windows. This behavior is in contrast with the Windows NT versions of the BSoD, which prevents the user from using the computer until it has been powered off or restarted (usually automatic).

The most common BSoD is displayed on an 80×25 text-mode screen, which is the operating system's way of reporting an interrupt caused by a processor exception; it is a more serious form of the general protection fault dialog boxes. The memory address of the error is given and the error type is a hexadecimal number from 00 to 11 (0 to 17 decimal). The error codes are as follows:[32]

  • 00: Division
    fault
  • 01: Startup Error
  • 02: Non-Maskable Interrupt
  • 03: Shutdown Error
  • 04: Overflow Trap
  • 05: Bounds Check Fault
  • 06: Invalid Opcode Fault
  • 07: "Coprocessor Not Available" Fault
  • 08: Double Fault
  • 09: Coprocessor Segment Overrun
  • 0A: Invalid Task State Segment Fault
  • 0B: Not Present Fault
  • 0C: Stack Fault
  • 0D:
    General Protection Fault
  • 0E: Page Fault
  • 0F: Error Message Limit Exceed
  • 10: Coprocessor Error Fault
  • 11: Alignment Check Fault

Reasons for BSoDs include:

  • Problems that occur with incompatible versions of DLLs: Windows loads these DLLs into memory when they are needed by application programs; if versions are changed, the next time an application loads the DLL it may be different from what the application expects. These incompatibilities increase over time as more new software is installed. According to some people[who?], this is one of the main reasons why a clean install of Windows is more stable than an "old" one (or an in-place upgrade).
  • Faulty or poorly written device drivers.
  • Hardware incompatibilities.
  • Damaged hardware may also cause a BSoD.

In Windows 95 and 98, a BSoD occurs when the system attempts to access the file "c:\con\con", "c:\aux\aux", or "c:\prn\prn" on the hard drive. This could be inserted on a website to crash visitors' machines as a prank. In reality, however, they are reserved device names for DOS systems. Attempting to access them from Windows causes a crash, which in turn brings up said BSoD. On March 16, 2000, Microsoft released a security update to resolve this issue.[33]

One famous instance of a Windows 9x BSoD occurred during a presentation of a Windows 98

Plug and Play devices. This event brought thunderous applause from the crowd and Gates replied (after a nervous pause): "That must be why we're not shipping Windows 98 yet."[34]
