Question

我正在构建一个脚本，它将使用Windows Update自动查找，下载和安装更新。

我正在使用此代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using WUApiLib;
namespace update_script
{
class Program
{
    static void Main(string[] args)
    {
        UpdatesAvailable();
        EnableUpdateServices();//enables everything windows need in order to make an update
        InstallUpdates(DownloadUpdates());
        Console.Read();
    }
    //this is my first try.. I can see the need for abstract classes here...
    //but at least it gives most people a good starting point.
    public static void InstalledUpdates()
    {
        UpdateSession UpdateSession = new UpdateSession();
        IUpdateSearcher UpdateSearchResult = UpdateSession.CreateUpdateSearcher();
        UpdateSearchResult.Online = true;//checks for updates online
        ISearchResult SearchResults = UpdateSearchResult.Search("IsInstalled=1 AND IsHidden=0");
        //for the above search criteria refer to 
        //http://msdn.microsoft.com/en-us/library/windows/desktop/aa386526(v=VS.85).aspx
        //Check the remakrs section

        foreach (IUpdate x in SearchResults.Updates)
        {
            Console.WriteLine(x.Title);
        }
    }
    public static void UpdatesAvailable()
    {
        UpdateSession UpdateSession = new UpdateSession();
        IUpdateSearcher UpdateSearchResult = UpdateSession.CreateUpdateSearcher();
        UpdateSearchResult.Online = true;//checks for updates online
        ISearchResult SearchResults = UpdateSearchResult.Search("IsInstalled=0 AND IsPresent=0");
        //for the above search criteria refer to 
        //http://msdn.microsoft.com/en-us/library/windows/desktop/aa386526(v=VS.85).aspx
        //Check the remakrs section

        foreach (IUpdate x in SearchResults.Updates)
        {
            Console.WriteLine(x.Title);
        }
    }
    public static UpdateCollection DownloadUpdates()
    {
        UpdateSession UpdateSession = new UpdateSession();
        IUpdateSearcher SearchUpdates = UpdateSession.CreateUpdateSearcher();
        ISearchResult UpdateSearchResult = SearchUpdates.Search("IsInstalled=0 and IsPresent=0");
        UpdateCollection UpdateCollection = new UpdateCollection();
        //Accept Eula code for each update
        for (int i = 0; i < UpdateSearchResult.Updates.Count; i++)
        {
            IUpdate Updates = UpdateSearchResult.Updates[i];
            if (Updates.EulaAccepted == false)
            {
                try
                {
                    Updates.AcceptEula();
                }
                catch (Exception)
                {
                    // Write a line to tell the user that an error occured with accepting this Eula
                    Console.WriteLine("Det oppsto en feil under akseptering av en Eula");
                }
            }
            UpdateCollection.Add(Updates);
        }
        //Accept Eula ends here
        //if it is zero i am not sure if it will trow an exception -- I havent tested it.

        UpdateCollection DownloadCollection = new UpdateCollection();
        UpdateDownloader Downloader = UpdateSession.CreateUpdateDownloader();

        for (int i = 0; i < UpdateCollection.Count; i++)
        {
            DownloadCollection.Add(UpdateCollection[i]);
        }

        // Define outside try-catch statement
        UpdateCollection InstallCollection = new UpdateCollection();
        try
        {
            Downloader.Updates = DownloadCollection;
            Console.WriteLine("Downloading Updates");
            IDownloadResult DownloadResult = Downloader.Download();
            for (int i = 0; i < UpdateCollection.Count; i++)
            {
                if (DownloadCollection[i].IsDownloaded)
                {
                    InstallCollection.Add(DownloadCollection[i]);
                }
            }
        }
        catch (Exception)
        {
            // Error occured, tell the user
            Console.WriteLine("An error occurred while downloading the updates. Please reboot and try again.");
        }
        return InstallCollection;
    }
    public static void InstallUpdates(UpdateCollection DownloadedUpdates)
    {
        try
        {
            UpdateSession UpdateSession = new UpdateSession();
            UpdateInstaller InstallAgent = UpdateSession.CreateUpdateInstaller() as UpdateInstaller;
            InstallAgent.Updates = DownloadedUpdates;

            //Starts a synchronous installation of the updates.
            // http://msdn.microsoft.com/en-us/library/windows/desktop/aa386491(v=VS.85).aspx#methods
            IInstallationResult InstallResult = InstallAgent.Install();

            Console.WriteLine("install block over");
            // Check if a reboot is required
            if (InstallAgent.RebootRequiredBeforeInstallation)
            {
                // Reboot
                Console.WriteLine("Reboot required");
            }
        }
        catch (Exception)
        {
            // An error occured
            Console.WriteLine("An error occured while trying to install the updates. Try again but remember to run as administrator");
        }
    }
    public static void EnableUpdateServices()
    {
        IAutomaticUpdates updates = new AutomaticUpdates();
        if (!updates.ServiceEnabled)
        {
            Console.WriteLine("Not all updates services where enabled. Enabling Now" + updates.ServiceEnabled);
            updates.EnableService();
            Console.WriteLine("Service enable success");
        }


    }

}
}

我认为它第一次运行时运行良好，但它第二次引发了异常。

以管理员身份运行时，会发生此错误：

此外，这样的脚本是否需要以管理员身份运行？

感谢您的帮助！埃里克

我使用以下VBscript：

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

WScript.Echo "Searching for updates..." & vbCRLF

Set searchResult = updateSearcher.Search("IsInstalled=0 and Type='Software'")

If searchResult.Updates.Count > 0 Then

   WScript.Echo "List of applicable items on the machine:"

   For I = 0 To searchResult.Updates.Count-1
       Set update = searchResult.Updates.Item(I)
       WScript.Echo I + 1 & "> " & update.Title
   Next

   WScript.Echo vbCRLF & "Creating collection of updates to download:"

   Set updatesToDownload = CreateObject("Microsoft.Update.UpdateColl")

   For I = 0 to searchResult.Updates.Count-1
       Set update = searchResult.Updates.Item(I)
       WScript.Echo I + 1 & "> adding: " & update.Title 
       updatesToDownload.Add(update)
   Next

   WScript.Echo vbCRLF & "Downloading updates..."

   Set downloader = updateSession.CreateUpdateDownloader() 
   downloader.Updates = updatesToDownload
   downloader.Download()

   WScript.Echo  vbCRLF & "List of downloaded updates:"

   For I = 0 To searchResult.Updates.Count-1
       Set update = searchResult.Updates.Item(I)
       If update.IsDownloaded Then
          WScript.Echo I + 1 & "> " & update.Title 
       End If
   Next

   Set updatesToInstall = CreateObject("Microsoft.Update.UpdateColl")

   WScript.Echo  vbCRLF & _
   "Creating collection of downloaded updates to install:" 

   For I = 0 To searchResult.Updates.Count-1
       set update = searchResult.Updates.Item(I)
       If update.IsDownloaded = true Then
          WScript.Echo I + 1 & "> adding:  " & update.Title 
          updatesToInstall.Add(update)    
       End If
   Next

   WScript.Echo "Installing updates..."
   Set installer = updateSession.CreateUpdateInstaller()
   installer.Updates = updatesToInstall
   Set installationResult = installer.Install()

   'Output results of install
   WScript.Echo "Installation Result: " & installationResult.ResultCode 
   WScript.Echo "Reboot Required: " & installationResult.RebootRequired & vbCRLF 
   WScript.Echo "Listing of updates installed and individual installation results:" 

   For I = 0 to updatesToInstall.Count - 1
     WScript.Echo I + 1 & "> " & updatesToInstall.Item(i).Title & ": " & _ 
                  installationResult.GetUpdateResult(i).ResultCode         
   Next

   If installationResult.RebootRequired = True Then
      Reboot(".")
   End If

Else
    WScript.Echo "There are no applicable updates."
End If

WScript.Quit



Function Reboot(StrSrv)
   Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate,authenticationLevel=Pkt,(Shutdown)}!\\" & StrSrv & "\root\cimv2")
   Set colItems = objWMIService.ExecQuery("Select * from Win32_OperatingSystem",,48)
   For Each objItem In colItems
        WScript.Echo objitem.Reboot
   Next
End Function

我使用以下包装器并安排它每周运行一次。我最近为Windows 10修改了它，它现在启用/禁用Windows Update服务以在脚本未运行时限制更新。我喜欢在发生问题时保留更新日志。
