If there's one color guaranteed to strike fear into the hearts of Windows users, it's blue. But as one Twitter sleuth has discovered, the iconic and always alarming "blue screen of death" is going green, and not because Microsoft is feeling festive. The new crash screen was spotted in a recently leaked preview version of Windows 10 (build 14997, to be exact), which isn't expected to be formally released until early next year. Microsoft's Matthijs Hoekstra has confirmed the color change is specific to test builds released through the Windows Insider program, which makes sense. Where bugs and crashes are reported, Microsoft will immediately be able to distinguish between problems with consumer Windows 10 builds, and those found on early, less stable preview builds.
