How to Enable or Disable Web Site Access to Language List in Windows 10

Some web sites on the Internet may access the list of installed languages in Windows 10. They use this information to provide a localized content, and switch to your native language, so you don't have to customize your preferences for each web site individually.

If you are not happy with this default behavior, Windows 10 includes a special option to prevent web sites from accessing the language list for you user account.

There are two methods you can use, including Settings and a Registry tweak. We will review both methods.

1. Open the Settings app.
2. Go to Privacy > General.
3. On the right, turn off or on the option Let websites provide locally relevant content by accessing my language list.
4. You can now close the Settings app.
