Microsoft has pushed the very first Windows 10 Redstone 3 preview Build 16170 to insiders in Fast Ring. You can read the changelog of the build by clicking here. As expected from initial preview builds for any major Windows 10 update, the Build 16170 brings changes in OneCore, the underlying structure for Windows 10.

This means lots of bugs and issues and less focus on new features and UI changes. The build 16170 brings its own share of officially known issues. But there may be many more which are covered by the list posted by Microsoft.

In case you are worried about these bugs and issues and but still want to continue as an insider, choose Slow Ring by going to Settings–>Update & Security—>Windows Insider Programme. In case you want to stay out of Redstone 3 updates you can choose to stay back on Creators Update by opting for Release Preview Ring.

In case you want to see the official listed known issues before making up your mind to go for Build 16170, check them below.

Windows 10 Redstone 3 Build 16170 Known Issues:

  • Narrator will not work on this build. If you require Narrator to work, you should move to the Slow ring until we get this bug fixed.
  • Some Insiders have reported seeing this error “Some updates were cancelled. We’ll keep trying in case new updates become available” in Windows Update. See this forum post for more details.
  • Some apps and games may crash due to a misconfiguration of advertising ID that happened in a prior build. Specifically, this issue affects new user accounts that were created on Build 15031. The misconfiguration can continue to persist after upgrading to later builds. The ACL on the registry key incorrectly denies access to the user and you can delete the following registry key to get out of this state: HKCU\Software\Microsoft\Windows\CurrentVersion\AdvertisingInfo.
  • There is a bug where if you need to restart your PC due to a pending update like with the latest Surface firmware updates, the restart reminder dialog doesn’t pop up. You should check Settings > Update & security > Windows Update to see if a restart is required.
  • Certain hardware configurations may cause the broadcast live review window in the Game bar to flash Green while you are Broadcasting. This does not affect the quality of your broadcast and is only visible to the Broadcaster. Make sure you have the latest graphics drivers.
  • Double-clicking on the Windows Defender icon in the notification area does not open Windows Defender. Right-clicking on the icon and choosing open will open Windows Defender.
  • Surface 3 devices fail to update to new builds if a SD memory card is inserted. The updated drivers for the Surface 3 that fix this issue have not yet been published to Windows Update.
  • Pressing F12 to open the Developer Tools in Microsoft Edge while F12 is open and focused may not return focus to the tab F12 is opened against, and vice-versa.
  • The Action Center may get into a state where dismissing one notification unexpectedly dismisses multiple. If this happens, please try rebooting your device.
