install ipc-daemon and postmaster as Windows services

I installed postgreSQL7.4 on Windows XP. I rebooted the machine, and
could not log into psql any more. I have to go through ./configure,
make, make install .... all over again. I guess that I need to install
ipc-daemon and postmaster as Windows services. I find some instruction
from internet as follows:

$ ipc-daemon --install-as-service
$ cygrunsrv --install postmaster --path /usr/bin/postmaster --args "-D
/usr/share/postgresql/data -i" --dep c-daemon -- msig --user postgres
--shutdown
$ cygrunsrv -S ipc-daemon # actually this step is optional
$ cygrunsrv -S postmaster

I notice that ipc-daemon should be ipc-daemon2 in vs. 7.4. But I cannot
find cygrunsrv in path/usr/bin/ directory. Can you tell me whether above
scripts are still valid for installing postgreSQL7.4? If they are, what
is the equivalent for cygrunsrv? If they are not, what are the scripts
for installing ipc-daemon and postmaster as Windows services?

Thanks
