Hi,

if your Windows installation should support multiple langauges you can install some Windows language pack.

Language packs, formerly known as MUI, are installable on Windows 7 Enterprise and ultimate and Windows 8/8.1.

The Download locations for individual language packs are:
Windows 7
Windows 8

Or, if you have a MSDN account, download the Language Pack DVD with the whole compilation.

Install the language pack in batch mode with the following command line, for example the german one:

C:\>dism.exe /online /add-package /packagepath:D:\langpacks\de-de\lp.cab

Deployment Image Servicing and Management tool
Version: 6.1.7600.16385

Image Version: 6.1.7600.16385

Processing 1 of 1 - Adding package Microsoft-Windows-Client-Refresh-LanguagePack-Package~31bf38....

[==================         32.7%                          ]

reboot the system after installation.

Check for installed languages

C:\Windows\system32>dism /online /Get-intl

Reporting online international settings.

Default system UI language : en-US
System locale : de-DE
Default time zone : W. Europe Standard Time
Active keyboard(s) : 0407:00000407, 0409:00000409
Keyboard layered driver : PC/AT Enhanced Keyboard (101/102-Key)

Installed language(s): de-DE
Type : Fully localized language.
Installed language(s): en-US
Type : Fully localized language.

The operation completed successfully.

Now you change the UI from command line language by  intlcfg.exe, which is included in the Windows Automated Installation Kit (WAIK) or form the Regional Settings Control Panel intl.cpl.

 

To installing the language pack by GUI start:

lpksetup.exe

by selecting language lp.cab file.
