Both "dsound.dll" and "hdaudio.inf" are present on my Win10XPE, but when I run drvload \hdaudio.inf on Command Prompt, it returns "DrvLoad: 无法载入 X:\windows\inf\hdaudio.inf (错误 0x80070103)。" What is wrong with it? However, sound files can be opened with VLC Meida Player portable, and sound can be heard.
My VLC Meida Player portable is only 34.3 MB and works fine on Win10XPE. Would you consider adding it into Wim Builder?
As to copying the script into a folder, what is the difference between "\Startup\BeforeShell\" and "\OSInit\"?
Will the script be run earlier than one in "\Startup\"?
