在 Windows（Vista）中，查看文件夹时，右键单击某个项目，会出现菜单“使用 Windows Media Player 播放”。
如何设置使此类子菜单不显示？
（但我不确定是否要卸载 Windows Media Player）
如果需要修改注册表我没有问题，只是需要知道在哪里......
答案1
相关条目在注册表中出现多次，但只需删除一个位置即可禁用上下文菜单条目。此外，上下文菜单条目针对不同类型的媒体文件和文件夹单独存在，具体取决于它是音频、图像还是视频。最后，有单独的条目用于播放 WMP 中的项目并将其添加到 WMP 播放列表中。这会产生需要删除的十二种排列（实际上只有十种，因为似乎没有针对图像文件的条目，只有针对图像文件夹的条目）。
以下是从文件和文件夹的所有三种媒体类型中删除两个命令的方法：创建一个包含以下内容的 .reg 文件并运行它。

将它们添加回来需要更长的时间（如下），因此您可能需要备份它们。
如果您想要保留上下文菜单条目，但只想删除加速器 ( P)，以便可以轻松粘贴文件而不必先通过 WMP 条目，则需要修改不同的注册表条目：
In this key:
[HKEY_CLASSES_ROOT\Local Settings\MuiCache\149\52C64B7E]
Change this value:
"@C:\Windows\system32\unregmp2.exe,-9801"="&Play with Windows Media Player"
To this (or something else; the & marks the accelerator):
"@C:\Windows\system32\unregmp2.exe,-9801"="Play with Windows Media Player"
Similarly, the Add to WMP entry is:
"@C:\Windows\system32\unregmp2.exe,-9800"="&Add to Windows Media Player list"

我发现这个方法（win7）在Win 10（10586）上对我有用，而且比所有注册表编辑业务都没有那么可怕：http://www.freewaregenius.com/how-to-remove-windows-media-player-from-the-windows-7-right-click-context-menu/
答案3
赶紧跑：
regsvr32 /u wmpshell.dll
这将取消注册 Windows Media Player shell 扩展，从而删除使用 WMP入口。
答案4
不要忘记删除
HKEY_CLASSES_ROOT\SystemFileAssociations\Directory.Audio\shellex\ContextMenuHandlers\WMPShopMusic
删除音频目录上下文菜单中的“在线购买音乐”。
