Not sure if this will work but it did for me when my PC was using US language I changed it permanently in the UK English.
Just go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nls\Language . Scroll down the menu to the right until you come to "Default" which will read "0409". Change this to "0809". That's it! Now if you use the en-GB language media creation tool, lo and behold you have the option to keep personal files and apps.
If you can find this registry entry in Chinese then you can try changing it to 0409 English US or 0809 English UK.
I can’t guarantee this will work so please create a disk image before attempting, if you feel this is too much to try then please do not attempt.
