IMPORTANT<\/b>: This notice only affects environments where Scan Cab is used to check for update compliance.<\/div>\n
<\/div>\n
The April 2026 Scan Cab was made available at 4:30 PM PT today, April 14, 2026. The Scan Cab can help determine<\/a> whether a Windows device needs to install necessary security updates released by Microsoft without first connecting to the Windows Update service. <\/div>\n
 <\/div>\n
How this affects your organization:<\/b><\/div>\n
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.<\/div>\n
  <\/b><\/div>\n
What you need to do to prepare:<\/b><\/div>\n
You can download and deploy the April 2026 Scan Cab via the usual processes. For detailed guidance, see the Additional information section below.<\/div>\n
<\/div>\n
No action is required on environments where Scan Cab is not employed. 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.<\/div>\n
