Microsoft has accidentally broken the Windows Media Creation Tool (MCT) just a day ahead of Windows 10 end-of-life. The company confirmed this case on its official documentation for Windows 10 22H2, which is perhaps the last update for that document page that we will see. "The Windows 11 media creation tool version 26100.6584, released September 29, 2025, might not work as expected when used on Windows 10 devices. The media creation tool might close unexpectedly, displaying no error message," says Microsoft page, adding the clarification about MCT "The media creation tool is used to create a bootable USB or DVD which can be utilized to perform a reinstall or clean install of Windows 11 on a new or used PC. Note that the Windows 11 media creation tool is not currently supported on Windows 10 devices that use Arm64 processors."

Of course, Microsoft offers a workaround. You can download bootable Windows 11 installation media directly from Microsoft's official download page here and select "Download Windows 11 Disk Image (ISO) for x64 devices" to get the ISO or follow the link for Arm64 build. Microsoft is preparing a fix that will be included in an upcoming update to the Windows 11 Media Creation Tool, and this document will be updated to reflect the resolution once that update is released. As a reminder, the Windows 10 reaches end-of-life tomorrow, October 14, when all security updates will stop and users would need to purchase separate extended security updates as a package, or switch to Windows 11.
