summary for non-techies**

The April 2025 Scan Cab, Wsusscn2.cab, is now available to help verify if Windows devices have the necessary security updates, especially for those not connected to the internet, by providing information about missing updates without including the updates themselves.

Direct effects for Operations**

Increased Security Vulnerabilities
Without proper preparation and deployment of the new Scan Cab, devices may remain unscanned for necessary security updates, leading to potential security vulnerabilities.
