Servicing stack update for Windows 8.1, RT 8.1, and Server 2012 R2: October 8, 2019

Summary

This update makes quality improvements to the servicing stack, which is the component that installs Windows updates. Key changes include the following:

  • Improves the Secure Boot revocation list (DBX) update experience to avoid multiple restarts when you deploy the DBX update on a device where the Credential Guard service is not running.

  • Addresses an issue in which the Secure Boot revocation list (DBX) is not applied when the Secure Boot allow list (DB) update is empty.

We strongly recommend you install the latest servicing stack update (SSU) for your operating system before installing the latest cumulative update (LCU). Installing servicing stack updates (SSU) makes sure that you have a robust and reliable servicing stack so that your devices can receive and install Microsoft security fixes.
