Windows 11 has changed its Blue Screen of Death (BSoD) to a Black Screen of Death, maintaining the BSoD abbreviation but adopting a new design that aligns with Windows 11's aesthetic. The new interface features a black background and a message stating, "Your device ran into a problem and needs to restart," along with a stop code for error information. Microsoft is testing this redesign in the Release Preview channel, aiming to improve user experience during crashes. The updated design removes the frowny face and QR code, which were previously part of the BSoD. Concerns have been raised about the new design's similarity to a standard Windows update screen, potentially causing confusion among users.
