Getting this update is like giving an older car a necessary tune-up and new parts to make sure it runs safely and doesn’t break down unexpectedly.

Why It Matters

It’s important because older computers, like those running Windows 10 version 21H2, can still get security fixes even after official support ends. For example, some fixes address “critical” issues that could allow attackers to take control of a computer.
