How to find world region (or country) or language from the windows registry?

Question

I'm working with a very old installer that can read Registry entries but has a difficulty (complex) time executing Windows APIs.

I'm trying to detect whether the PC it's being installed on is in Australia.

Any ideas?

Answer 1

This key:

HKEY_USERS.DEFAULT\Keyboard Layout\Preload

sets the default language for the login screen

The different country codes are listed here:

Answer 2

From my testing and the MSDN page below, this will work:

HKEY_CURRENT_USER\Control Panel\International\sCountry ="Australia"

This corresponds to setting in the Region Options ("Select an item to match it' preferences".

This has the advantage of also being able to be read from a non-admin account.

Answer 3

To supplement: "HKEY_CURRENT_USER\Control Panel\International\sCountry" is only used for the notation format. You could also use. "HKEY_CURRENT_USER\Control Panel\International\Locale" and link it to a table.

The notation cross-table:

The current location is stored in "HKEY_CURRENT_USER\Control Panel\International\Geo\Nation"

The location cross-table:
