Microsoft’s popular Blue Screen of Death (BSOD) now changes to Black Screen of Death in the Windows 11 operating system, first reported by The Verge. The BSOD is caused when the Windows get some errors like hardware or memory failures by showing an error message in the Blue screen before restarting the computer.
The BSOD checks for errors on the kernel level that tells the screen provides information on why is the system is crashing in the first place and displays it in an easily understandable way with a QR code which was introduced in 2016 to make searching for the problems the easiest way. In 2016, Microsoft showed BSOD color in green which is only used for builds, and the same green color Microsoft uses in Windows 11 Insider builds.

Looks like Microsoft has been testing a new color for this screen by turning off all the lights and changing it to black color from its blue color, the most popular error screen color in Windows. According to The Verge report, Microsoft will soon start matching the new boot process and screens and the shutdown screen to all black.
So it is unclear when Microsoft will change the color for BSOD and when it will be rolling out to Windows. I’m not sure what’s the reason behind it the color change, but I’m guessing the new Windows 11 could go with a better choice because of Windows 11 new design.
