Microsoft added BSOD (Blue Screen Of Death) or Blue Death Screen (BSOD) to the Windows 8 operating system in 2012. Later, in 2016, a QR code was added as an add-on to that BSOD. Similarly, Microsoft introduced a blue Death Screen for Windows 10. This made it easier for computer technicians and users to identify computer hardware and memory errors.
However, Microsoft has decided to replace the existing BSOD with a black background for the new Windows 11 operating system.
According to Verge Technology, Microsoft is working on a different version of the Windows 11 operating system than all previous operating systems.
