If you want to download the latest Windows 11 25H2 (preview build) before it's officially released to the public, you can download the ISO directly from Microsoft through the Windows Insider Program.

Join the Windows Insider Program:

Go to Settings > Windows Update > Windows Insider Program.

Sign in with your Microsoft account and choose the Beta Channel or Dev Channel.

Restart your PC if prompted.

Visit the Insider ISO download page:

Open your browser and go to:

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

Select Edition and Build:

Scroll down to the "Select edition" dropdown.

Look for Windows 11 Insider Preview (Beta Channel or Dev Channel) — it will include a build like 26200.xxx or newer, which corresponds to the 25H2 version.

Click Confirm.

Download Windows 11 25H2 ISO:

A 64-bit download link will appear. Click to start downloading the full ISO file (around 5.5–6 GB).

Install or Upgrade:

You can now mount the ISO in Windows and run setup.exe to upgrade. Or create a bootable USB from Windows 11 25H2 ISO.
