As the title say, how can I do it ?

I has made a decision to uninstall Vidalia and use only tor.exe to run as a relay. I have tried to install Tor into the service so it is not going to disturb me. But every time I tried to install Tor service, it will run using "NT AUTHORITY\LocalService" account. Tor said that the torrc is stored into service user (means "NT AUTHORITY\LocalService"), I tried google to find the directory of "NT AUTHORITY\LocalService" but found nothing. So anyone have any idea on how can I change the torrc for "NT AUTHORITY\LocalService" user ?

Thank you all for the good answers, but I already solved my problem. After doing some trace using Process Monitor on my tor.exe service, it looks like my tor service data is stored on C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\tor\, I'm happy man now. ;)

Also to add up a solution for future reference, I got this error message when trying to run tor.exe as a service Service failed to start : An exception occurred in the service when handling the control request. is because of permission problem. The DataDirectory that I set in my torrc file is currently on the my account and another user process (tor.exe that running under LocalService) can't access DataDirectory files. So to fix it up, just set your DataDirectory on main directory on your local disk like C:\torDatadDir\. ;)

It sounds like you're trying to run a Tor Relay as a Service on Windows.

Looking at the Windows Service FAQ, it looks as though you can tell Tor to use a specific torrc when installing the service, for example tor --service install -options -f C:\torrc, this is the recommended way of modifying the torrc for a Windows Service installation.

    Thank you for the help, I already tried that, but every time I run the command (with custom torrc), this error is out on the screen Service failed to start : An exception occurred in the service when handling the control request. Commented Nov 6, 2013 at 21:39

On my 2003 server I have Tor running as a service on the LocalService account. The Tor data directory is in the C:\Documents and Settings\LocalService\Application Data\tor folder. If you can't navigate to the C:\Documents and Settings\LocalService folder in the file explorer you have to type it in the address bar.

  • Thank you for your replied, I'm not using Windows Server of XP now, and I already search for that folder `C:\Users\LocalService` but its show nothing. Commented Nov 6, 2013 at 21:42
