Hi, I'm trying to get the Auto HDR feature within Windows 10. I joined the insider program and have even gone so far as to use an enablement package to get on 21H2 and there is still no Auto HDR function visible within Windows 10. I have looked but cannot find a way to update to dev channel 21337. How do I go about accomplishing this without updating to 11? Thanks.

You can create the ISO file from here:
Select language for Windows 10 Insider Preview 10.0.21337.1010 (rs_prerelease) amd64 - UUP dump
This tutorial shows you how to build the ISO file:
UUP Dump - Download Windows Insider ISO | Windows 11 Forum
Don't worry that it is on the Windows 11 site, it just shows you how to build the ISO file. If you start with the link I provided you will get 64-bit Windows 10 version 10.0.21337.1010
Thanks for the help fellow veteran! Checking Flight Hub, I see that there is actually a newer pre-Win 11 Active Development Build:
https://docs.microsoft.com/en-us/win...er/flight-hub/
Select language for Windows 10 Insider Preview 10.0.21390.2025 (co_release) amd64 - UUP dump
Once I select my edition the options on the next page are slightly overwhelming. I have selected "Download and convert to ISO" but there are many conversion options, should I select any of these other than "Include Updates"?
Summary for Windows 10 Insider Preview 10.0.21390.2025 (co_release) amd64, English (United States), Windows Pro - UUP dump
Actually, having a look at the tutorial is helpful, thank you so much for this!

Update: the download package was only 4mb in size, I was expecting 2.89gb, is there any error here?
No. The download package only contains the scripts needed to create the ISO file. You have to run the .cmd file in order to create the ISO file. Step 11 from the tutorial:
11. The ZIP archive will be extracted to a new folder, which will be opened automatically. Run the uup_download_windows.cmd file:
I figured it out, thanks. I also posted this question over on reddit and received the concerning answer that once the old dev builds expire I will experience constant reboots:
How to update to Dev Channel 21337? : Windows10
Is this true?
Thanks again
Yes. You have to stay on non-expired builds. But there should always be a non-expired build available to upgrade to.

Whoa, is there any indication that a build will expire or will I just experience a boot loop sequence one morning? 21390 is the latest Pre 11 Active Developer Build, so if this were to happen what recourse of action would I have at that point? I don't understand why Auto HDR isn't being released for Win 10, it's only in the Dev Build.
