i upgraded from win 7 to win 10 in early august. no problems. i\’ve been installing all updates since then and installed updates always showed status of updates. after installing fall update i noticed my update history was erased and any updates since, like defender definition files, don\’t appear in the list. only one update is listed: Security Update for Internet Explorer Flash Player for Windows 10 Version 1511 for x64-based Systems (KB3103688) installed on 11/14/2015.
I have exactly the same problem; no update history except the flash one.
