答案1
新安装后出现错误代码 0x80072EFE，因为 Windows 更新客户端不是最新的。
您可以从以下页面下载并安装最新版本：
将 Windows 更新代理更新至最新版本 - Windows 客户端 | Microsoft Docs
但与其他人一样，我只能建议您切换到 Win 10。
答案2
Windows 7 已经彻底完蛋了。甚至连安全更新都不再有。
如果需要，您所能做的就是下载并安装 SP1。Microsoft 仍然有这个功能。
如果您的机器足够强大（旧版 Windows 7 机器可能不够强大），请将其升级到 Windows 7。据我所知仍然免费。
答案3
我在安装 Windows 7 Service Pack 1 后遇到了这个问题。经过一番研究，我发现，升级所需的两个更新导致了这个问题，如果你从 Microsoft Catalog 网站下载它们，你就可以开始以常规方式获取其余的更新。问题是你无法使用 IE 访问 Catalog 网站，所以你必须安装另一个浏览器。安装 FireFox 是最简单的方法，因为你也不能使用更现代的安装程序。
