We have released Windows 10 Insider Preview Build 17074 for PC to Windows Insiders in the Fast ring and for those who opted in to Skip Ahead. Please note that the same block for AMD processors as explained here is also in place for this flight.
You can find more information for Bug fixes and known issues on the blog here.
Please avoid using with AMD processors:
We have a known bug that can cause a device with an AMD processor to be put in a no-boot state, either after upgrade or a clean install.
I found a note on our blog post Windows 10 (PC) Insider Preview (Build 17074)
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.
