Microsoft Accidentally Breaks Windows 10 to Windows 11 Upgrade

Microsoft has inadvertently broken the Windows 11 Media Creation! Tool (MCT), a key upgrade path for Windows 10 users, ahead of Windows 10's end-of-life.

As Windows Latest observed, the latest MCT version fails to work on Windows 10 PCs when attempting to upgrade to Windows 11. Although workarounds exist, no fix timeline has been mentioned.

With Windows 10 officially ending support on October 14, 2025, users are urged to upgrade to Windows 11 to maintain security updates and bug fixes. After this date, Windows 10 PCs will remain functional but become more vulnerable to security risks.

Windows 10 users will not receive free security updates or bug fixes after October 14, 2025.

A rush to install Windows 11 is expected, especially for those with compatible PCs, as the upgrade deadline approaches.

Author's summary: Microsoft breaks Windows 10 to Windows 11 upgrade tool.
