Microsoft has released a major security update for Windows, warning users to install it as soon as possible. The update fixes several serious issues, including one already being used by hackers.
The biggest change is to Secure Boot, a feature that helps protect your computer when it starts up. For the first time in 15 years, Microsoft is replacing old security certificates from 2011. These will expire in June 2026, so users need the newer 2023 versions to stay protected.
The update now lets you check your Secure Boot status in the Windows Security app using simple color indicators (green, yellow, or red). However, a green checkmark alone isn’t enough—you also need a message confirming all updates are complete.
Starting in May, users will also get alerts if their system is not ready before the deadline.
There’s another change getting attention: on some Windows 11 devices, Microsoft Edge may automatically open after the update. Some users have criticized this, saying it feels forced and hard to close.
Overall, the update is important for security, especially for older systems, and Microsoft is urging all users to stay up to date.
