我正在使用 WUAPI 搜索、下载和安装 Windows 更新（目前未使用 WSUS 服务器）。我正在使用具有特殊映像（Windows 10）的 VM 对其进行测试，该映像缺少多个更新（目前为 8 个）。我以管理员身份启动程序并提升权限以避免出现问题。它搜索更新，列出它们，下载它们并安装它们而不会出现任何错误。在我的情况下完成后，不需要重新启动。（出于测试目的，我内置_maxDownloadAndInstallSize = 1因为累积更新和功能更新需要很长时间才能安装:/) 但是当我现在打开我的 Windows 更新对话框时，它仍然显示它想要更新。此外，已安装的更新不会出现在历史记录中。我试图重新启动，但这也无济于事。当我再次执行我的程序时，它会毫无问题地安装下一个更新。情况是一样的。系统无法识别其中的任何内容。我也尝试过一次安装。它没有改变任何东西。
如果我的概念是错误的，或者我有什么有趣的许可问题，你知道吗？
对我来说，“完成”已安装的更新似乎缺少一些东西，所以一切都得到了同步。
我的代码（对不起，这只是实验性代码，因为我有问题，一些检查已经完成了好几次......）
