Jsizzle,
Boot into Windows and go to Control Panel-> Language -> Advanced Settings
Under Override for Windows Display Language, set it to English (United States)
Under Override for default input method, set it to English (United States) – US
Save your changes.
Once I made this change, the only chinese I see in Windows is my Office 365, which I am pretty sure I must have messed up.
There are still a couple of hard coded dialogs that are in chinese, such as the OS selector dialog, but my Windows updates are always in english.
Good luck !!
