Thank you for giving us this opportunity today.

We are concerned about the Secure Boot certificate expiration issue. In Japan, we manage approximately 100,000 PCs as well as servers located throughout the country. If a large number of devices were to become unbootable at the same time, it would have a serious impact on our business continuity. Therefore, we would like to take preventive action before any issues occur.
