Windows8.1上找不到wmp.dll的符号

Question

当试图在Windows8.1上加载用于wmp.dll的调试符号时，symchk显示它们在Microsoft符号服务器上不存在(请参见下面)。我还安装了Windows8.1 x86 32位零售符号，它包含所有其他WMP文件(wmplayer、wmpeffect、wmpshell等)的符号，但不包含wmp.dll的符号。

我也发了一封电子邮件到著名的windbgfb [at] microsoft [dot] com地址，但没有得到回应.还有其他方法可以要求微软提供这些符号吗？

顺便说一下，我的wmp.dll版本是12.0.9600.17415，我很确定这仍然是Windows8.1附带的原始版本。没有安装包含更新版本的Windows更新。

Answer 1

好吧，我找到答案了。我的怀疑是对的。由于对DRM的关注，微软没有为WMP.dll提供PDB。你必须在没有PDB的情况下解决问题。
