Hello,
This issue is not related to Windows for Business or Windows 365 Enterprise. It is specifically about obtaining the official installation media for Windows 11 Pro.
To perform a clean install, you need to download the Windows 11 Media Creation Tool directly from Microsoft. The tool allows you to create bootable USB or ISO media that can be used to install Windows 11 Pro. The download is available on Microsoft’s official site under the “Download Windows 11” section. Once you run the tool, you can select “Create installation media (USB flash drive, DVD, or ISO file) for another PC.” During installation, the edition will be determined by the product key you enter. If you provide a Windows 11 Pro key, the setup will install Pro rather than Home.
Here is the official Microsoft download page: microsoft.com/en-us/software-download/windows11
Make sure you have a valid Windows 11 Pro license key ready, as the Media Creation Tool itself does not provide a key—it only prepares the installation media. If your device already has a digital entitlement for Pro, the installer will automatically recognize it during setup.
I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!
