Actually, it would not! In Windows, keyboard layout settings are (or at
least can be) specific to a program. So you may have an English setting for
one program and a French setting for another. There is a default setting,
which is used for new programs, so that killing and restarting Emacs would
indeed restore the original setting.

To the OP: you should certainly check out the Windows keyboard layout
settings. The key combo that switches settings can be set by the user.
There are a bunch of possible options here, such as shift-alt (which IIUC
is the default one) or shift-ctrl, which are needed in Emacs to access
certain shortcuts, e.g., M-% or M-$. Using any of those functions will
switch the layout.

The keyboard layout settings should also have the option to put an icon in
the task bar, like Ralf said, so you can see which setting is active.

You may also disable all keyboard layouts except the French one, in which
case switching would not be possible.
