我使用此代码来获取待处理的 Windows 更新以及更新的大部分信息：

 static List<PendingUpdate> GetPendingUpdates()
    {
        var updateSession = new UpdateSession();
        var updateSearcher = updateSession.CreateUpdateSearcher();
        updateSearcher.Online = false; //set to true if you want to search online

        List<PendingUpdate> pendingUpdates = new List<PendingUpdate>();
        try
        {
            var searchResult = updateSearcher.Search("IsInstalled=0 And IsHidden=0");
            if (searchResult.Updates.Count > 0)
            {
                Console.WriteLine("There are updates available for installation");

                foreach (IUpdate windowsUpdate in searchResult.Updates)
                {
                    PendingUpdate update = new PendingUpdate();
                    update.Title = windowsUpdate.Title;
                    update.Description = windowsUpdate.Description;
                    update.Downloaded = windowsUpdate.IsDownloaded;
                    update.Urls = new List<string>();
                    foreach (string url in windowsUpdate.MoreInfoUrls)
                    {
                        update.Urls.Add(url);
                    }
                    foreach (dynamic category in windowsUpdate.Categories)
                    {
                        update.Categories += category.Name + ", ";
                    }
                    pendingUpdates.Add(update);
                }
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine("ERROR");
            throw ex;
        }

        return pendingUpdates;
    }

我还使用此代码来了解计算机当前是否需要重新启动才能完成安装的更新：

 static bool needsRestart()
    {
        ISystemInformation systemInfo = new SystemInformation();
        return systemInfo.RebootRequired;
    }

现在我的问题是，是否有可能知道挂起的更新是否需要重新启动计算机才能完成？在第一个代码中，我得到一个IUpdate 对象，但在安装此更新后我没有看到有关需要重新启动的信息。我有办法获取这些信息吗？

对于异步安装，我使用这样的东西：

rebootRequired = false;

UpdateSession updateSession = new UpdateSession();
updateSession.ClientApplicationID = SusClientID;

IUpdateInstaller updatesInstaller = updateSession.CreateUpdateInstaller();
IInstallationJob job = updatesInstaller.BeginInstall(InstallProgressCallback, installComplete, installState);

// here is your installer code and the checking if the installation is completed

IInstallationProgress jobProgress = job.GetProgress();

for (int updateindex = 0; updateindex < updatesInstaller.Updates.Count; updateindex++)
{
    IUpdateInstallationResult updateInstallResult = jobProgress.GetUpdateResult(updateindex);

    rebootRequired |= updateInstallResult.RebootRequired;
}

if(rebootRequired)
{
    // any of the updates need a reboot
}
