Windows 10 Insider Preview Build 17074 for PC Available

Microsoft has released a new update Build 17074 of Windows 10 to public which comes with new features, bug fixes and improvements. This is the 10th Insider Preview build of Windows 10 released after the Fall Creators Update. This new build comes via new “RS4” (RedStone3) development branch.

RedStone 4

What’s New

Following are the new features, improvements and fixes in this build:

  • Now you can schedule quiet hours in Action Center
  • Start Menu now shows links to Documents and Pictures folders in left-side list by default
  • New embedded Handwriting Panel
  • Improvements to Settings app
  • Includes mitigations to protect from the Spectre and Meltdown vulnerabilities
  • Improvements to Region & Language section in Settings app
  • Improvements to Microsoft Edge web browser
  • Bug fixes and general improvements

Known issue

Following are the known issues in this build:

  • When users try to create a Microsoft Edge InPrivate window from inside a Mixed Reality headset, a regular window will get created instead. Users won’t be able to use InPrivate inside Mixed Reality in this build. InPrivate on desktop is not affected.
  • Microsoft is preparing for the inclusion of OpenSSH Server as a deployment mechanism in Developer Mode. However the UI code got checked in ahead of the components, and so while there is a “Use OpenSSH (Beta) for remote deployment” switch in the UI under Settings, it won’t work, and turning it on will break remote deployment to that device until the switch is turned off.
  • When you open Task View immediately after an upgrade, Timeline may not be visible. If you encounter this, wait 15-30 minutes and try launching Task View again.
  • The Windows Defender icon is missing from the system tray, even if it shows as enabled in Settings.
  • Certain devices may hang on the boot screen after upgrading. If this happens to you, go into the BIOS and disable virtualization.
  • Apps that come preinstalled with Windows may fail to update in the Store with error 0x80073CF9.
  • Audio playback from Microsoft Edge is sometimes unexpectedly muted. A workaround is to minimize Edge, count to three, and then restore window.
  • Upgrading to 17063 or later builds sometimes causes Settings / Privacy / Microphone, Camera, etc. to flip to “disabled”, which breaks camera and microphone access. A workaround is to manually turn them back on.
