Windows – How to change Windows language in Windows 7 Professional

How can I change the Windows language from Spanish to English in a Windows 7 Professional?

Please note that this is not Enterprise or Ultimate version. So the normal way using a MUI is not possible.

Best Answer

The installation of additional languages is normally not possible - unless you upgrade to Windows 7 Ultimate or Enterprise.

However, it can be done. But it will violate your Windows EULA.

Instructions

  1. Download the MUI (Multilingual User Interface) for your Language. I downloaded the hu-HU package on C:\lp.cab. You have to change the path and language shorthand to your own
  2. After the download completes, open a command line prompt as administrator and type

    DISM /Online /Add-Package /PackagePath:C:\lp.cab
    bcdedit /set {current} locale hu-HU
    bcdboot %WinDir% /l hu-HU  
    
  3. Open regedit.exe and delete the en-EN key under

    HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlSet / Control / MUI / UILanguages

  4. Reboot
