强制 Windows Update 使用过滤器检查更新以避免某些类型的更新？

我需要创建一个程序来检查并安装重要更新

是否可以仅在有更新可用时才创建弹出窗口？

目前我正在使用此代码来检查更新：

Set updateSession = CreateObject("Microsoft.Update.Session")

Set updateSearcher = updateSession.CreateUpdateSearcher()
Set updateDownloader = updateSession.CreateUpdateDownloader()
Set updateInstaller = updateSession.CreateUpdateInstaller()

Do

  WScript.Echo
  WScript.Echo "Searching for approved updates ..."
  WScript.Echo

  Set updateSearch = updateSearcher.Search("IsInstalled=0")

  If updateSearch.ResultCode <> 2 Then

    WScript.Echo "Search failed with result code", updateSearch.ResultCode

  End If

  If updateSearch.Updates.Count = 0 Then

    WScript.Echo "There are no updates to install."
    WScript.Quit 2

  End If

  Set updateList = updateSearch.Updates

  For I = 0 to updateSearch.Updates.Count - 1

    Set update = updateList.Item(I)

    WScript.Echo "Update found:", update.Title

  Next

  WScript.Echo

  updateDownloader.Updates = updateList
  updateDownloader.Priority = 3

  Set downloadResult = updateDownloader.Download()

  If downloadResult.ResultCode <> 2 Then

    WScript.Echo "Download failed with result code", downloadResult.ResultCode
    WScript.Echo

    WScript.Quit 1

  End If

  WScript.Echo "Download complete.  Installing updates ..."
  WScript.Echo

  updateInstaller.Updates = updateList

  Set installationResult = updateInstaller.Install()

  If installationResult.ResultCode <> 2 Then

    WScript.Echo "Installation failed with result code", installationResult.ResultCode

    For I = 0 to updateList.Count - 1

      Set updateInstallationResult = installationResult.GetUpdateResult(I)
      WScript.Echo "Result for " & updateList.Item(I).Title & " is " & installationResult.GetUpdateResult(I).ResultCode

    Next

    WScript.Quit 1

  End If

  If installationResult.RebootRequired Then

    WScript.Echo "The system must be rebooted to complete installation."

    WScript.Quit 3

  End If

  WScript.Echo "Installation complete."

Windows 更新 API 非常强大，但要确定哪个更新实际上“重要”并不容易 - 您的代码显示了对所有尚未安装的更新的非常简单的搜索。您可以列出更新包并查询 IUpdate 接口的属性（请参阅http://msdn.microsoft.com/en-us/library/windows/desktop/aa386099(v=vs.85).aspx）

您还可以查看 WuInstall（不久前有一个免费版本，但他们将其从网站上撤下，现在只有一个带有免费试用版的商业版本可用） - 它也确实在命令行工具中使用了 Windows 更新 API。请参阅http://www.wuinstall.com/和http://help.wuinstall.com/en/index.html

基本上，您可以使用 Windows Update API 完成 WuInstall 可以完成的许多（并非全部）事情，但它可能会为您节省大量的编程和调试时间。

顺便问一下，“创建弹出窗口”是什么意思？
