How to make TOR as Windows Service

Hi,

TOR and Privoxy, works good.

TOR Outbound
Where the protocol TCP
and direction is Outbound
and remote port is 9001-9004, 9030-9033, 9100
Allow

TOR Inbound
Where the protocol is TCP
and direction is Inbound
and remote address is localhost
and local port is 9050
Allow


Privoxy Outbound
Where the protocol TCP
and direction is Outbound
and remote address is localhost
and remote port is 9050
Allow

Privoxy Inbound
Where the protocol is TCP
and direction is Inbound
and remote address is localhost
and local port is 8118
Allow




Now my problem is how to make TOR as Windows Service?
Vidalia can make that just one click, but i don't want to install Vidalia.

Thanks.
