some of them might be located in the "view optional updates" section in Windows Update settings panel.
in my case it shows Microsoft Silverlight ready to download but it doesn't appear in Windows Update. Silverlight is obsolete now and unnecessary now.
i suspect that Eset pulls info from the Microsoft Catalog website and displays them. if you click "Check for Updates" in the Windows Update and it shows your device is up to date, then don't worry.
