Hello,

Thank you for your interest in Windows 10.

To assist you better I would like to know, what was the base language for your previous Operating system?



I would suggest you to follow the below steps and check if it helps.

Step 1: Remove the Existing language.

• 
  Press Windows + X on your keyboard.
  
• 
  Select Control panel.
  
• 
  Select language.
  
• 
  Click on the Option adjacent to the
  Existing language.
  
• 
  Click on remove under input method.
  

Step 2: Add English Language.

• 
  Press Windows + X on your keyboard.
  
• 
  Select Control panel.
  
• 
  Select language.
  
• 
  Click on Add language.
  
• 
  Add the English language from the given list.

Thank you Shawn, very much. I believe the following comments will save at least some readers a large amount of time:

1. If one is trying to change the System Default UI language (and not the displayed language of an individual user), then the relevant tutorial is not the one you cite above, but is instead: [url='https://www.windowsphoneinfo.com/threads/region-and-language-settings-copy-in-windows-10.6819/[/url] (How to Copy Region and Language Settings to Welcome Screen and New User Accounts in Windows 10)

2. If you're like me, you don't want to really change the default system UI language at all. Your problem is that you have in your hand an upgrade .iso, but the upgrade won't allow you to preserve apps setting and files because the 'edition' of the iso isn't the 'same' edition as your current installed Windows. And logic tells you this can't be the real reason you can't preserve files apps and settings, because OF COURSE the .iso is of a different edition -- that's why you using it at all, to UPGRADE.
The shameful truth is that it is the system default UI language which is likely to be different between the .iso and your installed Windows. None of the other language settings seem to matter, although YMMV. Rather than go through the rather delicate procedure in the tutorial just cited, i found that indeed if I just change the value of the "default" key of this tutorial, changing to the correct, desired, LCID (i.e. the one matching the upgrade .iso), then the command dism /online /get-intl reports the system default UI Language to be immediately changed. So you can proceed with the upgrade, and --miracle of miracles -- you can keep files apps and settings.

When the upgrade completes, it is probably safer to restore the registry value using he control panel Region settings in the tutorial mentioned in the previous paragraph. However you choose to do it, making the default system UI language agree between the current installation and the upgrade media was absolutely critical to keeping my apps settings and files.

 

Change default language

That tutorials are quite long to read. You really have two options:

Change default language in Settings (if tech only added English and set it default)




or change your install language (if tech was a bit advanced and change install (more than default) language to English:

See tutorial by Brink:
If you have to check which is install lang, there is very similar tut for this too.
