my environment

• I installed vim on Windows
• added the following directives at the end of the _vimrc file:

:colorscheme ron

:set guioptions +=d
:set guioptions -=m
:set guioptions -=T
:set guioptions -=r

They respectively:

• set the colorscheme to ron,
• enable dark mode,
• remove the menu bar,
• remove the tools bar,
• remove the right scrollbar.
