Summary

This update makes quality improvements to the servicing stack, which is the component that installs Windows updates. Servicing stack updates (SSU) makes sure that you have a robust and reliable servicing stack so that your devices can receive and install Microsoft updates.

IMPORTANT Windows 7 and Windows Server 2008 R2 have reached the end of mainstream support and are now in extended security update (ESU) support.

Verify that you have installed the required updates listed in the How to get this update section before installing this update. 

For information about the various types of Windows updates, such as critical, security, driver, service packs, and so on, please see the following article. To view other notes and messages, see the Windows 7 and Windows Server 2008 R2 update history home page.
