Where is the Atlas ISO file?
On this page
Atlas does not distribute premodified Windows ISO files. Get unmodified Windows media from Microsoft, then use one of these routes:
- Install with Atlas Manager: Install fresh Windows first, then let Manager prepare and apply Atlas.
- Create an Atlas ISO: Use Manager’s beta media tools to include the app, playbook, and optional saved settings in your own ISO.
- Install with AME Wizard: Apply the Atlas playbook through the alternative installer.
Is Atlas already installed inside a Manager-created ISO?
The ISO contains the setup files. Atlas is applied on the destination PC after Windows setup and sign-in, so Manager can check Windows and Store updates for the account using it. Internet access and security checks are still required, including in the before-desktop setup mode.
Which Windows ISO should I use?
For Atlas Manager’s ISO creation, use an unmodified Windows 11 25H2 x64 ISO containing a supported edition. Manager checks the release and included editions before building. See the media guide for the full requirements.
