However, the next monthly update (build 22000.346) for the original release of Windows 11 will change the color back to blue (via Windows Central), but the company isn’t detailing the reason. The official notes read: “Changed the screen color to blue when a device stops working or a stop error occurs as in previous versions of Windows.” The Blue Screen of Death usually appears when the system comes across an error that it cannot handle. When an error occurs, the screen turns blue, the system creates a dump file and shows an error code that network administrators can use to troubleshoot and fix software and hardware problems. The blue screen error (also known as bugcheck) made its first appearance during the 90s with the introduction of Windows 3.0, and even though it has evolved over the years, Microsoft always kept it blue. However, it was then updated to black to Windows 11, and now, it will be once again blue. All content on this site is provided with no warranties, express or implied.
