Microsoft breaks Media Creation Tool on the eve of Windows 10 end-of-life — company confirms Windows 11 upgrade tool 'might not work as expected', outlines alternatives

Microsoft's latest Windows Media Creation Tool (MCT) update has a bug where it may close unexpectedly without showing an error message, right before Windows 10's end-of-life on October 14. This issue affects the tool's functionality for preparing update media for Windows 11. Microsoft suggests using Windows Update or downloading a bootable ISO directly from their website as alternatives. The company is working on fixing the MCT problem, but users can utilize these workarounds in the meantime to upgrade to Windows 11.
