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（参见下文）。我还安装了Windows 8.1 x86 32-bit retail symbols，其中包含所有其他WMP文件（wmplayer，wmpeffects，wmpshell等）的符号，但不包含wmp.dll。
我还向着名的windbgfb [at] microsoft [dot] com地址发送了一封电子邮件，但没有得到回应。有没有其他方法可以要求微软提供这些符号？
BTW，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。没有安装包含较新版本的Windows更新。
