Windows 8.1 で wmp.dll のデバッグ シンボルを読み込もうとすると、symchk はそれらが Microsoft シンボル サーバーに存在しないことを示します (以下を参照)。Windows 8.1 x86 32 ビット リテール シンボルもインストールしました。これには、他のすべての WMP ファイル (wmplayer、wmpeffects、wmpshell など) のシンボルが含まれていますが、wmp.dll のシンボルは含まれていません。
また、既知のアドレスにメールを送信しましwindbgfb [at] microsoft [dot] comたが、応答がありません。これらのシンボルを利用可能にするように Microsoft に依頼する方法はありますか?
ところで、wmp.dll の私のバージョンは 12.0.9600.17415 です。これは、Windows 8.1 に付属していた元のバージョンであると確信しています。新しいバージョンを含む Windows Update はインストールされていません。
