As we suggested last week, Microsoft has finally pushed out a new Redstone 4 build to Windows Insiders in the Fast Ring. This time, it is just a small jump in build number, up to build 17134, and primarily addresses some reliability issues.
According to head Ninja Cat Dona Sarkar, this build has no new features and includes the fixes from KB4100375 as well as some additional general under the hood fixes for the OS. Microsoft also confirmed today that they discovered some reliability issues in prior builds (likely a blocking bug) that they wanted to fix, and this new build will help address this. Sarkar explains:
As Build 17133 progressed through the rings, we discovered some reliability issues we wanted to fix. In certain cases, these reliability issues could have led to a higher percentage of (BSOD) on PCs for example. Instead of creating a Cumulative Update package to service these issues, we decided to create a new build with the fixes included. This just reinforces that Windows Insiders are critical to helping us find and fix issues before releasing feature updates to all our customers so thank you!
Now that this build has been pushed out to the Fast Ring, you can expect it to roll out to both the Slow Ring, and eventually the Release Preview Ring soon. It also might as well roll out to non-Windows Insiders too once the Redstone 4 update is ready, but there's no telling for sure. There are definitely some busy times ahead, so fire up those machines and get downloading.
