The Register has had a play with Windows 10 preview build 14316, and when the blue screen of death (BSOD) came up, it surprisingly had a QR code, and a sad smiley face.
As of Windows 10 Insider Preview build 14316, when the operating system falls over, you get not only the sad ASCII smiley but also a QR square that contains an encoded URL that leads you to a webpage about your problem. Scan it with a smartphone or other handheld and your browser will be taken to the embedded web addresses.
Right now, it just points to windows.com/stopcode, which explains typical Blue-Screen-of-Death causes, but in future it could contain detailed information about the crash – or something a little more user-friendly than something like MACHINE_CHECK_EXCEPTION.
Pop over to The Register for peek.
