在 Windows 8.1 上找不到 wmp.dll 的符号
No symbols found for wmp.dll on Windows 8.1
当尝试在 Windows 8.1 上加载 wmp.dll 的调试符号时，symchk 显示它们在 Microsoft 符号服务器上不存在（见下文）。我还安装了 Windows 8.1 x86 32-bit retail symbols，它包含所有其他 WMP 文件（wmplayer、wmpeffects、wmpshell 等）的符号，但不包含 wmp.dll.
我也向众所周知的 windbgfb [at] microsoft [dot] com 地址发送了一封电子邮件，但没有得到回复。是否有任何其他方式要求 Microsoft 提供这些符号？
顺便说一句，我的 wmp.dll 版本是 12.0.9600.17415，我很确定它仍然是 Windows 8.1 附带的原始版本。未安装 Windows 包含较新版本的更新。

好的，我得到了答案。我的怀疑是对的。由于 DRM 问题，Microsoft 不提供 WMP.dll 的 PDB。您必须在没有 PDB 的情况下解决您的问题。
