Recently, a pretty big Windows 10 build leaked online over the Christmas weekend. Over the past few days, there’s been a lot of new articles and tweets regarding some of the new features in the build. As it seems like, people weren’t able to find the “big change” in the build according to Microsoft employee Matthijs Hoekstra:

Cool to read all the new features people discover in the leaked builds, but they missed a big change!, Huge change!. curious when its found. — Matthijs Hoekstra (@mahoekst) December 27, 2016

Following his tweet regarding the big change, Hoekstra gave a hint regarding the feature — simply stating “Green!”. And it only took a little while for the big change to be unveiled as Microsoft enthusiast Chris123NT was able to find the new change fairly quickly.

So what’s the new big change? A Green Screen of Death, or GSOD. Microsoft is replacing the infamous Blue Screen of Death (BSOD) in Windows 10 with a green version — only for Insider Preview releases. According to Hoekstra, Microsoft is making the BSOD green on Windows 10 Insider Preview releases so that it’s easy to distinguish between Production and Insider releases.

This is likely a change that will help Microsoft while providing support to customers as they will easily be able to determine if a user is running an Insider release or a Production build. Previously, there wasn’t any way of determining if a user is running Insider builds on the BSOD, so a different color is definitely going to be quite helpful.

As to why Microsoft opted for the color green is yet to be known — but that frankly doesn’t matter.
