Hello everybody,

Microsoft surprise us again today! Last build to the Windows Insider Fast ring was just yesterday, but we’re following it up with another build today – Build 10159, releasing to the Fast ring.

Why two builds in two day? You might already know, Microsoft (MS) validate builds that they produce in internal rings where they’re used by engineers in OSG and Microsoft. If they pass all of MS criteria it will be available to Windows Insiders, first to Fast and then to Slow once MS know it’s a stable build. 

“We’d been using 10158 for almost a week and knew it was going to be a strong build, and the data backed that up so we released it yesterday. Hot on its heels though was build 10159, which in addition to more fixes (over 300 of them!), took in one very interesting change. We didn’t want to wait with 10158 so we went ahead and released that build while we were still evaluating 10159. As it turns out though, 10159 is also a great build and passes our criteria for the Windows Insider Fast ring.
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.” – g (from MS)

Microsoft Windows 10 Build 10159 will be available later this afternoon and it should be available everywhere by end of day. If you guys are downloading build 10158 when 10159 is published, you may get an error 0x80246017. If that happens, just reboot your PC, go back to Settings and check again and you should see 10159 offered to you.
