MCT Bug Affects Windows 10 as Support Ends

On 2025-09-29, Microsoft released an update to its Windows Media Creation Tool (MCT) that may cause it to close unexpectedly on Windows 10 systems. This issue arises as Windows 10 reaches the end of support on 2025-10-14.

Impact on Windows 10 Users

With Windows 10 support ending, users must explore alternatives to upgrade to Windows 11. Microsoft has confirmed that devices still running Windows 10 will cease to receive updates, support, and security fixes.

• The MCT bug was confirmed on 2025-10-10.
• Windows 10 support ends on 2025-10-14.
• Devices won’t receive further security updates after this date.
• Microsoft suggests alternatives for upgrading to Windows 11.

Alternatives for Windows 11 Upgrade

To circumvent the MCT issue, Microsoft recommends using Windows Update for the "Download and Install" feature, if compatible with the device. Alternatively, users can download the Windows 11 ISO directly.

For devices that do not meet the Windows 11 system requirements, users might employ third-party tools like Rufus to modify the ISO, though this carries some risk. Those unwilling to transition to Windows 11 might consider a current Linux distribution as a practical alternative, as suggested by experts.
