The June 2025 Scan Cab is available

IMPORTANT: This notice only affects environments where Scan Cab is used to check for update compliance.

The June 2025 Scan Cab was made available at 5:00 PM PT today, June 10, 2025. The Scan Cab can help determine whether a Windows device needs to install necessary security updates released by Microsoft without first connecting to the Windows Update service. 

The Wsusscn2.cab file is a cabinet file that is signed by Microsoft and contains information about Microsoft security-related updates. Devices that aren’t connected to the Internet can be scanned to see whether these security-related updates are present or required. The Wsusscn2.cab file doesn’t contain the security updates themselves so you must obtain and install any needed security-related updates through other means.

You can download and deploy the June 2025 Scan Cab via the usual processes. For detailed guidance, see the Additional information section below. No action is required on environments where Scan Cab is not deployed. However, please note that there might be non-Microsoft applications which utilize Scan Cab. Review the documentation for any software and update deployment tools used in your organization to understand if this is applicable in your environment.
