Microsoft has released the Windows 10 1909 KB5000850 cumulative update preview and a new KB5001205 Servicing Stack Update that resolves a Secure Boot vulnerability.
The KB5001205 Servicing Stack Update will automatically be installed by Windows Update to improve the update experience.
For users still running Windows 10 1809 users, Microsoft released the KB45000854 cumulative update preview but did not release an accompanying SSU update.
The SSU update fixes the issue by making sure prerequisite updates are installed in the proper order for the CVE-2020-0689 security update to install without errors.
SSU updates are mandatory and will automatically be installed by Windows 10 through Windows Update.
Note Devices using Windows Update for Business or that connect directly to Windows Update are not impacted.
