当我用以下 M(N)WE 编译时，pdflatex出现错误消息
pdflatex: Windows API error 1392: The file or directory is corrupted and unreadable.
pdflatex: Data: C:\Program Files (x86)\MiKTeX 2.9\tex/generic\dehyph-exptl
Compilation exited abnormally with code 1 at Sun Mar 01 11:09:12
代码：
\documentclass{article}
\usepackage{hyperref}
\begin{document}
Hello, world
\end{document}
当我注释掉\usepackage{hyperref}编译时，就可以了。 也可以
\usepackage[draft]{hyperref}。 明确要求\usepackage[pdftex]{hyperref}没有帮助。
这种情况几天前就开始发生了；据我所知，我的环境没有发生变化。
编辑。当我尝试编译不使用的更复杂的文档时，会发生相同的 Windows 错误hyperref。其他一些包可能正在调用文件
C:\Program Files (x86)\MiKTeX 2.9\tex/generic\dehyph-exptl
这是上述示例的（大部分）终端输出。如果有帮助的话，我可以提供完整的日志文件。
