_vimrc loading fails

Hi,

Under Windows 10, vim8.4.466 x86, I got _vimrc under $VIM and filereadable(expand('$vim/_vimrc')) returns 1

From help, it is written

MS-Windows $HOME/_vimrc, $HOME/vimfiles/vimrc
or $VIM/_vimrc <<< filereadable returns 1


I don't understand why I don't see my _vimrc loaded!

Thank you
Ni Va
