change MUI language pack in Windows 7 home and professional
Update: Die Deutsche Anleitung ist in den Kommentaren.
The final version of Windows 7 has hit the roads and users which had tested Windows 7 beta get disappointed: It is no longer possible to change MUIs, display language of Win 7, anymore – it seems.
First of all, changing display language (“installing MUI”) has been a feature limited to Ultimate and Enterprise versions. The beta was “Ultimate”, therefore changing was neat and easy possibly through the regions screen.
For all other versions you will have to get the appropriate “lp.cab”, i.e. from the Language Pack DVD. Then, type this in a command prompt as Administrator (change path and language code appropriately):
dism /online /add-package /packagepath:D:\langpacks\de-de\lp.cab
bcdedit /set {current} locale de-DE
bcdboot %WinDir% /l de-DE
After that, remove the registry folder HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\MUI\UILanguages\en-US. Reboot, bitteschön!
Update 2: If you get this error:
An error occured trying to open d:\de-de\langpacks\lp.cab Error:0×80070003 The System cannot find the path specified
… copy the lp.cab to C:\ (the root directory) and run dism from there. Remember that the command line shell must be run as Administrator.
