Hi,

In Window10, the Windows Update is divided into different categories, such as featrue updates, quality updates etc. The capture of Windows Update History page in system is below:

I have already known that I can get the list of updates by this API: IUpdateSearcher::QueryHistory

But how to get the categories of these updates like they are in the red rectangle of the capture?

I tried get_Categories in IUpdateHistoryEntry2, but it can't match the same categories as Windows Update History page. Would someone give me a suggestion?

Thanks.

    Hello,

    Quality update is not a a specific category. It includes security updates, critical updates, servicing stack updates, and driver updates. Refer to "Types of updates".

    You can check "WSUS Classification GUIDs" for a specific category like CriticalUpdates, SecurityUpdates etc.

    For query a collection of update like Quality update you see in the Settings -> View update history you can use IUpdateSearcher::Search() by specifying CategoryID as criteria paremeter.

    Or you can get "category" information from the title of an update (IUpdateHistoryEntry::get_Title) like this:
