Windows 10 build 18343 rolls out to Insiders on the Fast ring

Alongside a fresh new 20H1 preview build for Skip Ahead Insiders today, Microsoft is also pushing a new build from the Windows 10 19H1 development branch to Fast ring Insiders.

Coming in at build 18343, today's release doesn't include any major new features. However, there are some important fixes rolling out, along with a handful of known issues to be aware of. Here's a look at what's new.

General changes, improvements, and fixes for PC

  • We fixed the Connected Standby issue that resulted in us blocking PCs with Intel64 Family 6 Model 142 and Intel64 Family 6 Model 158 processor model. If your PC was unable to take Build 18342 from earlier this week due to having one of these processor models, you should be able to take this flight!
  • We fixed the issue that required an additional reboot when performing Reset this PC and selecting Keep my files on a device that has Reserved Storage enabled.

Known Issues

  • Launching games that use anti-cheat software may trigger a bugcheck (GSOD).
  • Creative X-Fi sound cards are not functioning properly. We are partnering with Creative to resolve this issue.
  • We're continuing to investigate reported issues in the night light space.
  • Some Realtek SD card readers are not functioning properly. We are investigating the issue.
  • In Windows Sandbox, if you try to navigate to the Narrator settings, Settings app crashes.
  • Mouse pointer color might be incorrectly switched to white after signing out and signing back in.
  • We're investigating reports of the Chinese version of multiple games not working.
  • If you install any of the recent builds from the Fast ring and switch to the Slow ring – optional content such as enabling developer mode will fail. You will have to remain in the Fast ring to add/install/enable optional content. This is because optional content will only install on builds approved for specific rings.

For the full rundown, be sure to check out Microsoft's release notes for more. Otherwise, if you're on the Fast ring, you can pick up build 18343 via Windows Update now.
