我需要在Windows計算機上獲取所有安裝的更新。我嘗試使用WUA API,但結果與我在控制面板 - 安裝的更新中看到的不同。我的代碼返回321更新,而在控制面板中我看到508這裏是我的代碼:如何獲取Windows安裝更新

誰能請解釋我是如何可以得到所有的更新?
謝謝。所以我的代碼應該只返回控制面板 - 程序和功能 - 安裝更新的Microsoft Windows部分的更新,對吧? – rudolfninja
@rudolfninja它不僅限於Windows。其他Microsoft產品和某些第三方組件(如驅動程序)的更新也可能通過Windows Update進行安裝。 – zett42
謝謝。我接到你了。還有一個問題。爲什麼我的輸出不同於wmic qfe get hotfixid輸出? WMI輸出與控制面板 - 程序和功能 - 安裝的更新中的Microsoft Windows部分具有完全相同的列表。順便說一句,你提到的功能有助於從控制面板獲得其他更新,但不是在Microsoft Windows部分。現在,我發現從本節獲得所有更新的唯一方法是WMI查詢。我的代碼中有什麼不正確? – rudolfninja
