Windows 10: Windows 10 not completely changing language

I download the English language pack on Settings > Time & Language > Language and set it as a preferred. I also changed the Windows display language. On administrative language settings, I copied all the settings to Welcome screen and system accounts and New user accounts, and restarted my PC. Still, some stuff like the Start Menu are still in the original language which is Brazilian Portuguese. And even the "Welcome" message after logging in is still in the original language.
Is there anything I can do without having to do a clean install with the English language?

Windows 8.1 update changed the language, can't change back

Maybe, these will help... it seems it is a common enough problem.

Language packs are no longer available after you upgrade to Windows 8.1

And, sort of the same here --> Add a language or keyboard

Quote from above MS web page:

Spoiler Download and install language packs
You'll need to download the language pack if you want to make a language your Windows display language (that's the language you see most often in Windows and apps).

• Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
  (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.)
• Tap or click Time and language, and then tap or click Region and language.
• Tap or click a language that says Language pack available underneath, and then tap or click Options.
• Tap or click Download. The download process might take a while, depending on your PC and the size of the language pack.
  If you want to make this your display language, see the next section "Change your Windows display language".

Change your Windows display language

Windows language not completely changed

Language packs are getting better,in Windows 10 they are if you ask me, using several language packs, they are as close to perfect as possible.

That being said, deep down some elements remain in original language. A good example in addition to those details you mentioned is Local Users and Groups manager (lusrmgr.msc); in screenshot you can see that although I have changed original German to English with a language pack, all user groups are still in German:




This means that if I for instance would like to add a user to Remote Desktop Users, I would need to use group's German name Remotedesktopbenutzer instead.

To completely change system and display language on an existing installation keeping your user account, personal files and installed applications, you need to force Windows to run the setup (OOBE) again. To do this, open Run dialog and type %windir%\system32\sysprep\sysprep.exe to open Sysprep:




Accept defaults, click OK to start Sysprep:



Sysprep will restart your PC, going through setup once again. After restart you will be asked which language you want to use to setup Windows, listing the original language (German in this case), and all installed languages (language packs, UK English in this example case). Select your preferred language:




Set region and language preferences, click Next:




Skip the product key, it will not be needed. An activated Windows will remain activated when sysprepped:




You need to set up a temporary account, I in these cases set up a local account called Dummy:




You can't use any existing user name; as I had a local user before Sysprep, setup will not accept it:




That's it. When on desktop, sign out from temporary Dummy account, sign in to your original account and remove Dummy account.

Looking the Local Users and Groups manager now you will see that even those group names have been changed to English:




The two Start tile section headers are still in original language, change or remove them, as will be a few live tiles of native Windows apps. They will change to English when you start using them, or you can remove these tiles if they are not needed.

Everything else is now in English. Don't forget to backup Windows before starting!

 

language changed windows 10

Hi Keith,

I realize the inconvenience you are facing with language settings.

To assist you better, please provide the information:

• 
  What is the make and model of the wireless keyboard?
  
• 
  Is the keyboard layout changed or the complete Windows interface is changed to Arabic?
  
• 
  Are you able to login to the computer?
  
• 
  Have you installed Windows 10 with single language edition?
  

To confirm, if it is single language edition you have to reinstall the Operating System or if it is multiple language you have to download the language pack of your choice and make it as default.

If only the wireless keyboard layout has changed then, I suggest you to add a keyboard layout in Windows 10 from the below steps:

• 
  Type settings in the search bar and press enter.
  
• 
  Go to Time & language.
  
• 
  Click on Region & language.
  
• 
  Choose the language you wish to add as keyboard layout.
  
• 
  Click on Options.
  
• 
  Click on Add a keyboard.
  
• 
  Select the keyboard layout you want to add.
  
• 
  Restart your computer.
  

Please note, that to change a keyboard layout using the following method, you need to have more than one keyboard layout added to your language settings. See how to add a keyboard layout in Windows 10 if you need help with that.

Press Windows logo key + spacebar.

Please get back to us with the update on the issue to assist you further.

Thank you.
