Windows 10 1809 – Region/language registry keys

windows 10windows-registry

I got two simple question for you guys today, hopefully you can help me since I haven't been able to find it myself for some reason.

For Windows 10 1809 what registry keys controls the following settings?:

Settings > Time & Language > Region > "Country or region"
Settings > Time & Language > Language > "Preferred language" order of languages

I've tested quite a bit with the following keys, but they do not seem to control any of these five settings:

HKLM\SYSTEM\CurrentControlSet\Control\Nls\Locale > "(Default)" key
HKLM\SYSTEM\CurrentControlSet\Control\Nls\Language > "Default" key
HKLM\SYSTEM\CurrentControlSet\Control\Nls\Language > "InstallLanguage"
key HKCU\Control Panel\International\Geo > "Nation" key
HKCU\Control Panel\International > "Locale" key
HKCU\Control Panel\International > "LocaleName" key

That is five settings.

HKLM\SYSTEM\CurrentControlSet\Control\Nls\Language!Default is set by Regional Control Panel, Administrative tab, Language for non-Unicode Programs.

HKLM\SYSTEM\CurrentControlSet\Control\Nls\Language!(Default) is set by Regional Control Panel, Administrative tab, Language for non-Unicode Programs. (There can be multiple values for this).

HKLM\SYSTEM\CurrentControlSet\Control\Nls\Language!InstallLanguage is set by Windows setup and used by the Windows upgrade process.

HKCU\Control Panel\International!Locale and LocaleName are set by Regional Control Panel, Formats, Format.

HKCU\Control Panel\International\Geo!Nation is set by Regional Control Panel, Location, Home Location.

Windows 10 1809:

Settings > Time & Language > Region > "Country or region"

Updates:

HKCU\Control Panel\International\Geo!Name
HKCU\Control Panel\International\Geo!Nation

Settings > Time & Language > Language > "Preferred language"

Does not update any one registry key/value. Sample:

HKCU\Software\Microsoft\CTF\SortOrder\Language\00000000
HKCU\Software\Microsoft\CTF\SortOrder\Language\00000001
HKCU\Software\Microsoft\CTF\SortOrder\Language\00000002

HKCU\Control Panel\International\User Profile\[langid]\CachedLanguageName

HKCU\Software\Microsoft\Internet Explorer\International\AcceptLanguage

HKCU\Keyboard Layout\Substitutes\[langid]

HKCU\Keyboard Layout\Preload\2

So if you're trying to determine what registry settings, you may have your work cut out for you.

Set Registry Keys from Domain Policy

It's perfectly acceptable to use Group Policy to push out registry changes via Preferences as squillman mentioned. Read up on Preferences before you start though, they don't behave in the same way as genuine Policies (sticky etc). Also, there's a bit of getting around the correct syntax to use in the policy template - get it wrong and you'll be scratching your head for ages trying to figure it out.

Server 2012r2 change login screen language with registry

These are suggestions, I haven't had to tackle this myself...
1) BCDBoot sounds the most promising, and may be the only thing necessary.

bcdboot %WinDir% /l nl-NL

2) Are these machines being built with an answer file? This says language can be specfied in the answer file. http://technet.microsoft.com/en-us/library/dd744569%28WS.10%29.aspx

3) Before a use logs in, settings are derived from HKEY_USERS.DEFAULT hive. You might try some of these:

HKEY_USERS\.DEFAULT\Control Panel\Desktop\MuiCached\MachinePreferredUILanguages
HKEY_USERS\.DEFAULT\Control Panel\International\sLanguage
HKEY_USERS\.DEFAULT\Software\Classes\Local Settings\MuiCache\448\52C64B7E\LanguageList

4) GPO has some "override" options, but it sounds a little overkill for this case. These would need to be set in a GPO linked to the OU the computer account resides in.
Computer Config/Windows Settings/Administrative Templates/Control Panel/Regional and Language Options
