It works but the problem is that to start the server you must load it 
from the gui. Instead since I want to start the server from my app, I 
need to understand how to load it manually. I tried starting 
postgres.exe but it's saying:

Execution of PostgreSQL by a user with administrative permissions is not
permitted.


You should use pg_ctl instead. That will take care of dropping any administrative rights 
the current user might have. I'm using a set of batch files to create a 
"portable" postgres, and I use pg_ctl for that purpose even with administrator 
account.

The server must be started under an unprivileged user ID to prevent
possible system security compromises.  See the documentation for
more information on how to properly start the server.

That0s strange, because the gui instead is able to load it so I'de 
like to know how can I do the same thing (and I can't find the source 
code of the ui).
I'd look in Local Users and Groups to see if this utility has created a 
special user account to run the postmaster under.  Also, after the 
GUI has startted it, use something like Process Explorer (from 
Microsoft, formerly SysInternals) to see what user the postgres process 
is running as.


my guess is you need to invoke postgres.exe with the appropriate 
arguments, such that it runs as that non-privileged user, see 
http://msdn.microsoft.com/en-us/library/ms682431(VS.85).aspx for one way 
to do this...
