Somewhere it was described as _one-line_ (for command line - bash???) -
backslash is used here to splitting parameter whith space into two
parameters:

regtool.exe -i set /HKLM/Software/Cygnus\ Solutions/Cygwin/heap_chunk_in_mb 1024

I don't it's good to do via octave `system' but you can try (in one line):

system('regtool.exe<sp>-i<sp>set<sp>/HKLM/Software/Cygnus\\<sp>Solutions/Cygwin/heap_chunk_in_mb<sp>1024')

Where you have to change <sp> for ' ' (space character). I wrote so to
prevent distortion by e-mail system. Remark also two backslashes - octave
interprets backslash sequences (so called escape sequences) - in this case
it'll convert \\ to \ as expected.

I don't how `system' is executed  on octave for Windows - maybe via
command/cmd? Then you can try use double quotes whithout backslash:

     "/HKLM/Software/Cygnus Solutions/Cygwin/heap_chunk_in_mb"
