You’ve done something to end up in this state. I wonder what?

That screenshot says you have the 26100 feature pack. What does it say when you type winver into search and click enter?

Side note: It also tells you the current Windows version at the top of the Command Prompt window.
Took me three years to notice that... LOL


It doesn't make me feel stupid though. I mean how often does MS, actually do something useful. :D

Weird. So you don't recall instigating the Insider channel preview?

I don't know, is it because you're PC is a Workstation? I am clueless to these things and to the Insiders program and it's Windows versions.
But this is interesting none the less, as you were running a Public release prior.

    …still on a horse.
I am confused. My system said I have 26120.xxxx.
26120 is the Insider Dev build. It shares a common set of system files with the public release of 24H2 26100. The insider features are turned on by an Enablement Package and the build number increased by 20.


This Enablement Package can be uninstalled to return it to 26100, and you can unenrol from Insider builds in Settings > Windows Update > Windows Insider Programme.

Thanks. From what I read online you can’t go from higher to lower build. Under window insider program I can’t select anything other than between Canary and Device.

Thanks. From what I read online you can’t go from higher to lower build.
The exception to this is when the build number has been increase slightly by means of an Enablement Package. This installs more like a CU than a feature update, no system files are replaced. Because both builds share a common set of system files you can revert to the lower build just by uninstalling the Enablement package.

Under window insider program I can’t select anything other than between Canary and Device.
You should see an option to stop receiving Insider builds too.
