Change Windows interface language "from script"

Question

Windows

Good afternoon! There was a problem: you need to conditionally change the display language of the user interface in Windows 2008 R2.
"Pitfalls" like re-login seem to be taken into account, it is understood that the required language is already installed.
The question is how can this be done "from the command line" - it doesn't matter, PowerShell, CLI, VBScript, through the Registry, through COM objects, ... - but only so that it can be done automatically.
I immediately warn you that it is not suitable for politicians, since it is not known to whom to hang which policy.

Answer 1

Regshot tracked the registry change when applying the new language (ru-RU) from the Windows 8.1 Control Panel, the following file was obtained (after cleaning the garbage):

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Control Panel\Desktop]
"PreferredUILanguagesPending"=hex(7):72,00,75,00,2d,00,52,00,55,00,00,00
; это ru-RU в hex

[HKEY_CURRENT_USER\Control Panel\Desktop\LanguageConfigurationPending]
"ru-RU"=hex(7):65,00,6e,00,2d,00,55,00,53,00,00,00,00,00
; это en-US в hex

checked on a clean system - applied the file, rebooted - the system changed the language from English. in Russian
99% that such a tweak will work for 2008 as well, because the architecture is identical.
well, import the tweak via reg
