    About WUA

  • What is WUA?

  • Definition from MSDN: Windows Update Agent (WUA) automatically updates itself when it is connected to a Windows Server Update Services (WSUS) server or to Windows Update. WUA can also be manually updated by using a signed installation package that is available from Microsoft.

  • In one word, use WUA you can control the procedure of updates updating your machine.

  • How to use WUA?

  • Because WUA is series of COM interface, so you can use it in many ways.

    1. In C#: you can call these functions directly via tlbImp. Or use class Type, such as Type.GetTypeFromProgID

    2. In PowerShell: New-Object –ComObject ProgId

    3. In C++, you can include <wuapi.dll>, use COM API, CoCreateIntance etc.
