Tutorial: How to change UI language for Windows 7 Professional

By default, the ability to change the UI language is only found in the Ultimate version of Windows 7. Those with the misfortune of buying a PC preinstalled with Windows 7 Professional, me included, did not have this ability. I decided that I had to replace the Japanese UI with an English one, and the only way was to hack it. Here’s how I did it;

Download the language pack that you want to install from here

Run CMD as administrator and type:

DISM /Online /Add-Package /PackagePath:[path to lp.cab];

eg. C:\DISM /Online /Add-Package /PackagePath:C:\Documents\Downloads\lp.cab

then:

bcdedit /set {current} locale (your new locale)

eg. C:\bcdedit /set {current} locale en-US

and:

bcdboot %WinDir% /l (your new locale)

eg. C:\bcdboot %WinDir% /l en-US

Then in registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\MUI\UILanguages

remove the key of the current language (in my case, jp-JP)

Reboot and you should boot up in the language of your choice.
