Nothing worse than getting a Blue Screen of Death aka BSOD when Windows has a critical crash due to hardware or software issue. Worse yet, the screen contained a cryptic message about what went wrong along with a long hexadecimal code. Coming in the Windows 10 Anniversary Edition Update (August 2016), the BSOD will include a QR code which can be scanned by a smartphone or tablet.
However, Microsoft has an opportunity here for aiding self-support when it comes to problem-solving a Windows installation as it could offer assistance via a website or even a dedicated app for troubleshooting using the QR code.
Ironically, the last time I encounter a BSOD was on a Windows 7 Frankenstein’s monster computer that I was trying to install Windows 10 Beta release on. That computer had always been plagued by BSOD which seemed to have subsided after I did a clean and pure install of Windows 7. The person who originally built the system installed Windows Vista then upgraded it to Windows 7 Ultimate, but it was only the 32-bit version (which made about half of the 8 GB of RAM unuseable). So then they installed Windows Vista again and then upgraded to the 64-Bit version of Windows 7 Ultimate. I have not encountered a BSOD on my Windows 7 laptop or even my Windows 8.1 desktop (Windows 8 introduced the kinder, gentler BSOD which added the 🙁 and did away with hexadecimal code).
