我不确定它是否与 KB3176493 有关，因为我找不到任何其他相关内容。我搜索了一整天，但只找到大量完全不相关的 Windows XP/8 帖子。无论如何，今天打开我的电脑发现它重新启动了。太好了，更新告诉我。然后我发现我的设备都不能用了！网络、蓝牙、USB 音频、USB 视频……全都消失了！设备管理器中出现了黄色的小感叹号。
我下载了网络/无线驱动程序并重新安装它们；它们工作正常。但是我的 USB 音频/视频设备都无法工作，我无法让它们工作。毕竟这些是系统设备；驱动程序应该包含在 Windows 中。但是我一直收到此错误：
我检查了一下，C:\Windows\INF\setupapi.dev.log发现以下内容：

该文件不存在。我安装了全新的 Windows 10 VM 来获取它，但...它在新安装中不存在！目录中有一个名为 USBAUDIO.sys 的文件System32\Drivers，但如果我尝试将其复制到此位置，我会收到另一个有关未签名 INF 文件的错误！
我搜索了好久，还是找不到解决办法。到底是怎么回事？
答案1
我终于找到了解决办法。总结我下载并安装了Windows10升级28084.exe来自微软网站。
关于我如何诊断此问题的完整描述可以在这里找到：

答案2
我犯了同样的错误“该系统找不到指定的文件”带有 USB 音频和 MTP 存储，但不是 28084（这只是表明我的系统是最新的），而是 Windows10Upgrade9252.exe 有帮助。
