Microsoft has updated the Blue Screen of Death (BSOD) in the latest Windows 11 preview build to now be the Black Screen of Death. The Blue Screen of Death has been included since Windows 1.0 was released in 1985 and has received various changes over the years adding error codes, the sad face, and most recently in 2016 QR codes. The new Black Screen of Death was likely introduced to blend better with modern systems and is functionally identical to the previous version. Microsoft had previously introduced the Green Screen of Death for Windows Insider Preview Builds so if you are running the Windows 11 preview and want to enable the updated BSOD you can set the DisplayPreReleaseColor Variable to 0 in the registry editor (HKLM\SYSTEM\CurrentControlSet\Control\CrashControl) and reboot.
