fmtutil in W32TeX saves formats in engine subdir.
(Therefore, I and Staszek decided not to use it because of
 the consistency with TL.)

My fmtutil.cnf is like
...
# Context formats:
cont-en pdftex cont-usr.tex --etex --8bit cont-en.ini
cont-en aleph cont-usr.tex --etex cont-en.ini
cont-en xetex cont-usr.tex --etex cont-en.ini
...

fmtutil --byfmt cont-en
makes all three cont-en.fmt's:

$TEXMFMAIN/web2c/pdftex/cont-en.fmt
$TEXMFMAIN/web2c/xetex/cont-en.fmt
$TEXMFMAIN/web2c/aleph/cont-en.fmt

while
fmtutil --engine xetex --byfmt cont-en
makes only

$TEXMFMAIN/web2c/xetex/cont-en.fmt

There are only small number of options compared to the script for Unix:

Commands:
 --all                      recreate all format, base, mem files
 --missing                  create all missing format, base, mem files
 --byfmt formatname         (re)create format for `formatname'
                            `base' and `mem' files can also be created
 --byhyphen hyphenfile      (re)create formats that depend on `hyphenfile'
 --showhyphen formatname    print name of hyphenfile for format `formatname'
 --version                  show revision number
 --help                     show this message

Options:
 --cnffile file             set configfile for fmtutil
                            default is `fmtutil.cnf'
 --fmtdir directory         set destination directory for format files
                            `directory' must be an absolute path
                            default is $TEXMFMAIN/web2c/$engine
 --engine texengine         specify the TeX engine (with --byfmt fmtname).
 --log                      save log file(s) in the TEMP directory

Best regards,
Akira
