在Win10PE中关联Potplayer比较简单，比如将你的Potplayer程序放在 Program Files 目录，那么按下面方法去执行就行了。

一、清除Windows Media Player文件关联

必须先清理WMP的文件关联，才能关联其他播放器。可以使用批处理：

:END
EXIT

二、使用Potplayer命令行参数关联文件

"X:\Program Files\Potplayer\PotPlayerMini64.exe" /RegisterAll

三、Potplayer其他个性化设置

Potplayer的个性化设置可以保存到 X:\Users\Default\AppData\Roaming\PotPlayerMini64\PotPlayerMini64.ini，在注册表有下面几个设置项可以调整：

PECMD代码：

\\皮肤
REGI $HKEY_CURRENT_USER\Software\Daum\PotPlayerMini64\Settings\LastSkinName=XMP-Gray_mini_W.dsf

\\禁止自动下载安装包
REGI $HKEY_CURRENT_USER\Software\Daum\PotPlayerMini64\Settings\AutoDownloadFile=0

\\禁止自动升级
REGI $HKEY_CURRENT_USER\Software\Daum\PotPlayerMini64\Settings\CheckAutoUpdate=0

\\设置语言文件
REGI $HKEY_CURRENT_USER\Software\Daum\PotPlayerMini64\Settings\LanguageIni=Chinese(Simplified).ini
