How to check currently used MUI Language from command

Today I spent another time to investigate how to achieve that. I googled out lot of sites, but most of them doesn't bring desired solution, even when they discussed exactly this problem:

http://www.visualbasicscript.com/Detecting-MUI-OSLanguage-m40687.aspx
http://www.autoitscript.com/forum/topic/117085-os-display-language-switcher/
... and some other

I tried also 'systeminfo', or registry ("HKEY_CURRENT_USER\Control Panel\Desktop\MuiCached"), or even wmic and so on... All of them responded mostly with system locales or which language OS was installed originally instead of telling which MUI is used.

This one finally help:

Easy solution:

reg query "HKEY_CURRENT_USER\Control Panel\Desktop" -v PreferredUILanguages

If you need this to store as variable just use FOR command with /F parameter:

FOR /F "skip=1 tokens=3" %%I IN ('reg query "HKEY_CURRENT_USER\Control Panel\Desktop" /v "PreferredUILanguages"') do SET Current_MUI=%%I
