How to remap the 'Alt gr' key on Windows?

In the past, pressing my Alt Gr key did the same as Ctrl + Alt. Now, pressing my Alt Gr key did the same as Alt.

I don't understand why it changed. How can I cancel this change ?

I probably use a keyboard shortcut. (Like alt + shift to switch from AZERTY to QWERTY)

Solution 1:

I accidentally disabled AltGr functionality too. After searching for a while, I found the following post:

Try pressing Shift+AltGr to toggle between different AltGr functions. Hopefully this solves your issue.
