我在这里编写了一个使用 WUA COM 接口（等）的应用IUpdateSearcher程序IUpdate。我使用此应用程序扫描可用更新、下载更新并安装它们。一切正常，直到我下载并安装一些更新，并有一些 ui 更新对话框。

我在使用 时获得了此更新IUpdateSearcher.Search()，我可以成功下载它（使用IUpdateDownloader.Download()），但是当我使用安装此更新时，IUpdateInstaller2.Install()我无法摆脱用户界面。

我的问题是 - 我怎样才能让它成为一个静默安装？

jvelez 有一个很好的答案，但它没有直接回答实际问题：“我怎样才能让它成为一个无声的安装？”

confi - 我首先建议最简单的方法：

static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.SetCompatibleTextRenderingDefault(false);
Application.EnableVisualStyles();

Thread thread = new Thread(() =>
{
Form1 form1 = new Form1();
form1.Visible = false;
form1.ShowInTaskbar = false;
Application.Run(form1);
});

thread.SetApartmentState(ApartmentState.STA);
thread.Start();
}
}

通过简单地隐藏您的 UI 来确保所有方法都在后台运行，这将为您提供一种使其静音的方法。

@Justin Choponis - 我需要做和confi一样的事情。WSUS 并没有为我的许多客户削减它。它不切实际且笨重。如果您有一个网络需要照顾并且一直在现场，那么 WSUS 会很有用，但我觉得它非常不令人满意。
