In µTorrent 3.0 has been integrated among other things the new feature "Remote". With this feature I have the option of remote control of the program μTorrent via a web interface.
First, I must adjust this new feature. For that I am going first to Options -> Preferences -> Remote, where I enable the checkbox next to "Enable µTorrent Remote Access". Afterwards I create an username and password. The web interface can be reached at the address https://web.utorrent.com. There you log in with the previously specified username and password.
If however I install µTorrent in the traditional way on the computer, I can use the new feature "Remote" without problems.
This I tested on a computer with OS Windows XP SP3.
