Description

Microsoft has released the KB5089573 preview cumulative update for Windows 11 versions 25H2 and 24H2, which comes with 30 changes, including performance and reliability improvements. [...]

Impact

This update does not address any security vulnerabilities and no exploits are known in the wild. Its impact is limited to improving system performance, reliability, and user experience. It also ensures continued Secure Boot functionality by updating expiring certificates. There is no direct security risk associated with this update.

Defensive guidance

This is an optional, non-security preview update intended for testing new features and improvements. Users and administrators can choose to install it to benefit from performance and reliability enhancements. Since it does not address security issues, it is not a required security patch. For security updates, users should continue to monitor official Patch Tuesday releases. No urgent action is required based on this update alone.
