Vim for Windows

After I installed vim 7 in my Chinese XP system, all the menu and messages were set to Chinese language automatically, but I'm familiar to the default English language, so I try to set it back. The command is add

:let $LANG='en'

in the source file. Thean all the messages are in English now.

But the GUI menu are still in Chinese, the method is simple

set langmenu=none
maybe the source of the menu is necessory.

source $VIMRUNTIME/delmenu.vim
set langmenu=none
source $VIMRUNTIME/menu.vim
