How to Manage Preferred Languages in Microsoft Edge via Registry or Preferences File?

fsfarimani Hi, if you want to set/manage your preferred languages programmatically with a given list of languages, you can either use

• group policies: 
  Administrative Templates/Microsoft Edge/DefinePreferredLanguages
• create a REG_SZ registry key:  HKLM\SOFTWARE\Policies\Microsoft\Edge\DefinePreferredLanguages

For details see https://learn.microsoft.com/en-us/deployedge/microsoft-edge-policies#definepreferredlanguages 

There you can provide a comma separated list in the order of your preferred languages, e.g. "en-US,en-GB,nl,fr" 
A list of the valid language values can be found here
