A new Windows 10 build heads to the fast ring. This time, it’s build 17074. As with the last flight, there is a block for AMD processors at this time. Be sure to read the known issues before installing, in case there is a show stopper in there for your specific case.

Known issues

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.
We’re 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 systray, 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 unminimize.
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.
