Hey, How do I get Windows 11 26H1, as I've still got 25H2? Kind regards, Damo

Hi, You either wait for the next update or go to the link that David posted above and download the ISO for build 28020, after the download open the folder and run Setup from there.

Hi, On the screen you see showing Beta, open Advanced options and you should see this: Pick the one that says Windows 11 version 26H1.

DysphasiaPV, Since you are posting to the Windows Insider forum, I assume you are enrolled in the Windows Insider program, with one of the Insider builds of the operating system. If so, then the easiest way to get the 26H1 build is to select it in the Settings > Windows Update > Windows Insider Program > then select Beta (or Experimental I suppose) > Advanced Options. Select 26H1 in Advanced Options. It should be available if you're in the Beta channel. Of course, if you're an Insider, it's also possible to use the ISO file for Beta 26H1, but the way I decribed is the easiest. You'll get 26H1 as a normal Windows 11 Feature Update, minimal fuss.

Hi, What Insider Channel are you in? 26H1 is only available to Insiders. Use WIN+R, type winver and post the build # you're on.

Please go to this link (not the catalog)

And download this ISO:

Mount the ISO, then open the file and click Setup.

I think I'll wait, because if I go to that link and download the ISO, when I try to install it, I get this error message:

So, do I wait for Windows Update to see that I changed it?

I had tried that method when it first came out and never got the 26H1, downloaded the iso and did it that way.

This is what my Insider screen on Windows Update looks like now. I'm on Beta.

And I still don't get 26H1

DysphasiaPV,

So, click on the pulldown for Advanced Options. That's where you'll see the 26H1 choice. It's not set by default. You have to select it.

Hi,

What Insider Channel are you in?

26H1 is only available to Insiders.

Use WIN+R, type winver and post the

Go here:

https://www.microsoft.com/en-us/software-download/windowsinsiderpreviewiso

download the Beta 26H1 build, mount the iso file and run setup to get to the 26H1 Insider version. That's the way I did it.
