Look for a safe place for Windows 11 24H2 ISO Download

Microsoft has moved on to Windows 11 25H2. That is why you can't download Windows 11 24H2 ISO image from Microsoft website.

Microsoft’s official Windows 11 download page now focuses on the latest version, 25H2, and so the ISO selector may only show 25H2 rather than 24H2. Official ISO downloads tend to be updated to offer the newest release, and older media isn’t always listed prominently once a newer version is out.

In practice, after a newer major version is released (like 25H2), Microsoft may remove or de-prioritize direct access to the previous version's ISO from the public download site. It’s part of their normal lifecycle; they want most users on the newer build for security and support reasons.

What you can do if you really need 24H2

If Microsoft’s download page no longer shows a 24H2 ISO:

Use Microsoft’s Media Creation Tool — it can generate an ISO and sometimes allows choosing older builds while connected to the official servers.

Check Microsoft Visual Studio / MSDN subscriber downloads if you have a subscription — older versions are often archived there.

Use a tool like UUP Dump to build a 24H2 ISO by pulling official files from Microsoft and creating your own image. (This still uses Microsoft’s source files but is a more advanced method.)
