We know Microsoft only allows ultimate Windows 7 users to enjoy multi-language user interface. Thanks to Martin Vogel, we can install the language pack on Windows 7 professional.
- Prepare your language pack DVD, insert it in D driver, here D is your DVD drive. Locate your required language pack. For example, if we want to install German language pack, the lp.cab file will have a path of D:\langpacks\de-de\lp.cab.
- Run command window with administrator privileges. To run it as an administrator, go to "all programs - accessories", right-click "command prompt" and choose "run as administrator".
- In the command window, type the following line and press Enter (dism"space"/online"space"/add-package"space"/packagepath:d:\langpacks\de-de\lp.cab), note that the space in between:
dism /online /add-package /packagepath:d:\langpacks\de-de\lp.cab
- When a message pops up and tells you the operation is completed successfully, press "Windows key + R" to call the run window, type in regedit to run the registry editor.
- Navigate to \HKLM\SYSTEM\CurrentControlSet\Control\MUI\ UILanguage\eu-us and delete the key eu-us.
- Restart your system, now your Windows 7 Professional should be switched to the German language version.
- To change the language of "Starting Windows", run the following command in the command window (still take the German as example):
bcdedit /set {current} locale de-de
bcdboot %WinDir% /l de-de
Update:
- It seems this trick works on home premium version as well.
- I have changed an English Windows 7 system into a Chinese one.
