Summary

This update makes quality improvements to the servicing stack, which is the component that installs Windows updates.

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. For general information on SSUs, please see the following articles:

Known issues

Restart stuck on "Stage 2 of 2" or "Stage 3 of 3"

After you install a servicing stack update together with other updates, a restart may be required to complete the installation. During this restart, you may find yourself stuck at a particular stage and see a "Stage 2 of 2" or "Stage 3 of 3" message.

If you experience this issue, press Ctrl+Alt+Delete to continue to log on. This should occur only one time and does not prevent updates from installing successfully.

Note In managed environments, such as by using Windows Server Update Services (WSUS), you can avoid this issue by deploying this update as a standalone update.
