Yes. Use:
DISM /Online /Get-Intl
DISM /Online /Remove-Package /PackageName:Microsoft.Windows.LanguagePack..._neutral...
If you need offline language packs, skip the shady "Extra" label and follow the official Microsoft path:
If you’ve ever browsed through MSDN downloads, a software repository, or a torrent site looking for deployment tools, you’ve probably stumbled across a strangely named file: Microsoft Windows 10 Language Pack Offline Install - Extra . It sounds official, but it also feels like a fan-made label. So, what exactly is this package, and should you trust it for your offline deployment needs?
No. The /Online flag requires a fully booted Windows 10. For WinPE, you must use DISM /Image: targeting an offline mounted Windows image.
