In a rare after-hours flight, Microsoft has released Windows 10 for PCs build 16294 to the Fast ring. This is the second build that was released this week - the first happening two days ago with 16291 - and if it's not entirely obvious, it's not available for those that chose the 'Skip Ahead' option that was available earlier this summer.
Being that the Fall Creators Update is slated to be released on October 17, there are no new front-facing features as Microsoft gears up for an RTM. 16294 does include one very important fix, which is for Surface Pro 3 users that were unable to boot up their machines with the previous two Fast ring builds.
Here's the full list of changes, improvements, and fixes:
This build has the fix for the bug that was causing some Surface Pro 3 devices to end up in a “unbootable” state where the Windows OS will not load and it appears to be stuck on a “spinning dots” screen. After installing this build, Surface Pro 3 devices should no longer get into this state. If you have a Surface Pro 3 in a bad state – follow the instructions on this forum post to get back up and running.
We fixed an issue on Dutch builds where explorer could go into a crash loop if an app-requested downloads notification popped up from OneDrive.
We fixed an issue where expand.exe couldn’t expand CABs that contained Japanese characters in the file name.
We fixed a race condition that could result in window content being transparent (but showing the window frame) or stale after unlocking your desktop.
We fixed an issue resulting in some Insiders seeing error 0x800B010C when attempting to upgrade to the last few flights.
In a previous build, Microsoft officially set the version number for the Fall Creators Update to 1709, which means that we can expect it to be finalized this month. Once that's official, we'll see it arrive in the Release Preview ring before it's offered to the general public on October 17.
To install today's build, head over to Settings -> Update & security -> Windows Update -> Check for updates. If you're not on the Fast ring yet, go to the Windows Insider Program tab and click 'Get started'.
