Windows 10 Build 14393.1670 Changelog:
This update includes quality improvements. No new operating system features are being introduced in this update. Key changes include:
- Addressed issue where Update History and hidden updates are lost and a full scan for updates happen after installing OS Updates 14393.1532 through 14393.1613, including KB4034658. Installing this update will not restore past update history or hidden updates for users who have already installed the listed updates.
