Build 10159 hits Fast ring
There were reports that Microsoft's Windows 10 Technical Preview Build 10158 released on Monday might be the last public version for Insiders before the operating system's July 29 release date, but that isn't the case. A day later, Microsoft's Gabe Aul announced the release of Build 10159 to Fast ring Insiders.
The way these releases work is Microsoft validates its builds in internal rings where they're used and tested by engineers. Once these builds pass testing, they're released to Windows Insiders, first to the Fast ring for early access and then later to the Slow ring once it's been deemed stable.
So, why release two builds in two days? According to Aul, one reason is because Build 10159 includes over 300 bug fixes. And the second reason is because it introduces "one very interesting change."
Aul didn't elaborate on what that change is, though reports around the web suggest it's a revised login screen with a new hero image for the OS.
"We could have held off on it and picked a later build to give you some time with 10158 but we thought that you’d want to see that one change… Let us know if we chose correctly, or if Fast suddenly got *too* fast with 2 builds in 2 days," Aul added.
Though both builds are Fast ring releases, Aul said about Build 10158 that there are no known "significant issues," just some minor ones. With Build 10159 including over 300 fixes, it's probably a pretty stable release, though we still wouldn't advise installing it on a mission critical system.
