"In Windows 10 IoT Enterprise LTSC, Microsoft incorrectly displays the end of life after the update on October 14, 2025!
What happened?
With the October update, Microsoft apparently accidentally set an EOL flag for Windows 10 Enterprise LTSC 2021 (version 21H2) and IoT Enterprise LTSC.
…
You can ignore the EOL warning as long as you are using the LTSC version.
Microsoft is expected to fix the issue with a future update.
No action is required for security-critical systems (e.g., industrial PCs, medical technology) as long as the LTSC version is installed correctly."
