For best DOS conventional memory, edit the windows\system32\config.nt
and autoexec.nt files.

In config.nt have (apart from the large number of REM lines) just
EMM = B=4000 RAM
(note the exact spaces - either side of the first = and before RAM,
none next to the second =) and

dos=high, umb
device=%SystemRoot%\system32\himem.sys
files=40
(or higher files= if needed)

and in autoexec.nt have

REM Install DPMI support
lh %SystemRoot%\system32\dosx

with other earlier lh lines REM ed out, and then any SET or PATH lines
that may already be present at the end.

This should give about 612K for a program, run from a shortcut made to
its .exe file. R-click the shortcut, Properties and on the Memory page
you can set an explicit value - rather than Auto - for any EMM or XMS
memory it may need, and for initial environment space
