Microsoft has just announced the release of a bug fixing update for the Windows 10 Insider build 18312, which was released last week for Fast Ring Insiders. If you have already installed the build 18312, you can check out Windows Update to download the preview build 18312.1007 (KB4487181). The company says that this will be a gradual rollout, so don’t worry if you’re not seeing this new build right now.

Here are the three bugs that Microsoft fixed in this new build:

  • We fixed an issue resulting in File Explorer unexpectedly having a lock on USBs when trying to safely eject them.
  • We fixed an issue resulting in frequent bugchecks (GSODs) in the last two flights, citing an error with bindflt.sys.
  • We fixed an issue where a password change can result in the next unlock hanging for AD users.

In a series of tweets, Windows Insider Chief Dona Sarkar said yesterday that the team was currently busy fixing other bugs, including some related to Windows Sandbox. It seems that some Windows Insiders are struggling to use the lightweight VM solution, and hopefully Windows Sandbox will be more stable in future builds.

If you manage to download the build 18312.1007 today, please let us know in the comments how is your experience after installing the new bits.

Update 11:30 AM PST: If you’re a developer, Microsoft also released the Windows 10 SDK Preview build 18312 today.
