Thanks to the introduction of a VGA driver in the kernel itself, the blue screen is now also shown in 640x480 graphics mode instead of 80x50 text mode.

The message was simplified in Windows 2000 to only include possible instructions for the user should they encounter the blue screen.

Originally, a system crash only resulted in the error code being printed out to the screen, although later during Windows NT 3.1 development it was extended to also display the stack trace and a list of loaded drivers and their base addresses.

Earlier builds merely print the error code to a debugger, if attached, and trigger a breakpoint in an infinite loop. The first known build to implement a blue screen is the October 1991 build. According to John Vert, the developer who originally wrote the code in the NT kernel that was responsible for controlling the screen in text mode, the white-on-blue color was chosen in order to match the MIPS' firmware display, as well as the default color scheme of the SlickEdit text editor many NT developers used at the time. On Windows NT, blue screens are also commonly known as STOP errors, referring to the *** STOP label that introduced the error code up to Windows 7. Early builds of Windows Me briefly replaced the "It is now safe to turn off your computer" with a blue screen at one point. The interface was also used in early Windows 98 builds for ACPI subsystem errors, which notably used a red background instead of blue. Windows 9x is unique in that it allows the user to continue after a system error, although it often resulted in an unstable system. Windows 95 and later uses the modal interface to report severe system errors instead of exiting to DOS, which earned it the blue screen of death nickname. Steve Ballmer wrote the original message for the Task Manager warning. The task manager allowed the user to terminate an unresponsive program, or if there's no unresponsive programs, simply allow the user to exit the screen or press Ctrl+ Alt+ Del again to reboot the system. The interface was also used for a simple task manager in Windows 3.1, which could be invoked by pressing Ctrl+ Alt+ Del while running Windows in the 386 enhanced mode. However, severe system errors still caused Windows to exit back to MS-DOS, similarly to the older versions.

In Windows 3.x, this was mostly used in situations where a program couldn't continue running until the user resolved an issue, such as device conflicts or disk swaps. The look of the modal dialog was virtually unchanged through the rest of the classic Windows series. Initially, it used a black background, although Windows 3.1 later changed it to blue.

This was a full screen message in text mode, which suspended Windows until being dismissed by the user. Whenever Windows did crash, it often resulted in a system hang or the shell returning back into DOS.Ī modal dialog for displaying important system messages was first introduced in Windows 3.0 and was mostly used by virtual device drivers in 386 enhanced mode. When early Windows is run on a newer version of MS-DOS, it will print out an "Incorrect DOS version" error message, followed by garbled contents of the memory during the boot before loading into the Windows shell, which is often thought to be a crash screen, however, it is only a bug in the logo code.

Contrary to popular belief, Windows 1.0 and Windows 2.x did not have a crash screen.
