Just two days after its previous Windows 10 Insider Preview release, Microsoft has queued up build 16294 for testers. Yep. The Windows 10 Fall Creators Update is almost complete.

“We are rolling out Windows 10 Insider Preview Build 16294 for PC to Windows Insiders in the Fast ring only (not Skip Ahead),” Microsoft’s Dona Sarkar noted. “This build might not be available for everyone as it rolls out so just be patient.”

Windows Insiders are known for their patience, so I’m sure that went well.

Anyway, there are no new features, of course. And Microsoft declines to hide the state of Windows 10 by not providing a known issues list to the public. But the firm did fix the following problems in this build, two of which were very widespread:

• This build has the fix for the bug that was causing some Surface Pro 3 devices to end up in a “unbootable” [not sure why this is in quotes, as those PCs were, in fact unbootable. –Paul] 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 do have a Surface Pro 3 in a bad state, you can follow the instructions on this forum post to get back up and running.
• This build fixes an issue resulting in some Insiders seeing error 0x800B010C when attempting to upgrade to the last few builds. I experienced this problem on my Surface Pro 4 for the last two builds, actually.
• This build fixes an issue on Dutch builds where explorer could go into a crash loop if an app-requested downloads notification popped up from OneDrive.
• This build fixes an issue where expand.exe couldn’t expand CABs that contained Japanese characters in the file name.
• This build fixes a rare condition that could result in window content being transparent (but showing the window frame) or stale after unlocking your desktop.
