Words I like to hear! Microsoft has released ISO files for the latest build in the Dev channel. That being Windows 11 build 25140, which just made its way out after quashing some bugs.
Insiders now have access to this new version of the preview, both direct and in ISO form.
The latter, of course, allowing them to deploy this build as a clean install on their test system or a virtual machine if they into that sort of thing. The clear benefit of these types of files is that you can install the latest preview without updating an existing installation.
And it is truly worth deploy this latest version of the preview.
For starters, build 25140 is part of the Sun Valley 3 development branch, which is the version of the OS that will be released to users next year in 2023 — as Windows 11 version 23H2. Meaning, this is where you need to be at if you want to test out the latest features that Microsoft is adding to the platform.
You know, things like tabs in File Explorer, and whatnot.
Since this official ISO release is only available to Insiders, you very much need to be enrolled in the Windows Insider Program to proceed. Log in with your Microsoft account at the link below in order to get the download link.
Another thing to keep in mind is that Windows 11 preview versions require activation via a genuine Windows key, just like the stable release of the operating system.
If you are interested in simply upgrading to build 25140, you can do so via Windows Update, as usual.
But if you want in on the ISO files to do a fresh install on your PC or virtual machine, then you can grab the bits that Microsoft has published on the official website.
