系统文件检查器无法完成扫描？

可能是什么问题呢？
由于磁盘检查（chkdsk）尝试/修复了一些错误，因此您的存储介质（硬盘）存在一些问题/错误，损坏了Windows OS相关文件。由于损坏的文件属于一个不重要的Windows更新，因此您可以选择修复或忽略它。但是要解决System File Checker失败的问题，我们应该修复与文件相关的扫描所引起的错误。

sfc /scannow 将尝试修复与文件相关的损坏，这种损坏在这种情况下会卡住。

sfc /verifyonly 将检查文件是否损坏，但不会尝试修复。

如果sfc命令无法修复损坏，您的下一个选择是在消除与存储介质相关的问题/错误之后，从原始介质中提取文件（或执行DISM）。

我该如何解决？
在这里，运行磁盘检查可解决与硬盘相关的问题，并且卸载或重新安装损坏的更新将修复文件损坏。以下是分析：

这指的是Windows更新的损坏：KB3068708（其更新，某些用户和作家将其列为“间谍补丁”之一，仅仅是因为它从系统中收集数据并将其发送到MSFT）。

通过应用此服务，您可以将Windows最新版本的好处添加到尚未升级的系统中。

您可以查看此更新是否在“控制面板”>“所有程序和功能”>“已安装的更新”中列出。如果找到它，则应右键单击它，然后选择“卸载”。如果您选择在下次检查Windows更新时安装它，它将被卸载并安装。如果未在“已安装的更新”中列出，请尝试以下操作：

wusa /uninstall /kb:3068708 /quiet /norestart
