Windows Insiders who were hoping to see a new Windows 10 Fast ring build this week may want to set their sights on next week instead. As happens occasionally, Microsoft has run into a blocking bug and doesn't expect to flight any new Fast ring builds this week. Windows Insider chief Dona Sarkar confirmed as much on Twitter, stating:
The green screen Sarkar refers to is the Green Screen of Death, the Insider version of the infamous Blue Screen of Death (BSOD) on shipping builds of Windows. Having your PC crash for simply connecting it to power is a pretty nasty problem to have, so waiting makes sense.
It's not all bad news for Windows Insiders, though. Microsoft this week shipped Windows 10 preview build 17025 to Slow ring Insiders, making it the first Redstone 4 preview build to hit the Slow ring. The release isn't packed with a ton of major new features, but Microsoft is only just getting started with testing the next big Windows 10 release; we'll see much more before it's ready for primetime.
