Many of us like torrenting as it allows us to download the contents without redownloading in case the internet connection is interrupted. For instance, if you are going to download a free, open source Linux distro like Ubuntu , you may want to use a free, intuitive, user-friendly, portable, customizable torrent client like uTorrent  (although not as pared down as some others). However, the recent versions of uTorrent feature advertisements, which is a turn-off. The good news is that the option to remove ads is available in uTorrent.
In this article, I will tell you how to do that. You can disable all ads including the top toolbar one as well as the one in the sidebar, which oddly (or, strategically?) are handled separately.
Disclaimer: Using uTorrent may not be illegal, but downloading illegal content is. This article does not encourage downloading contents if it is illegal in your country. Look before you leap!
Run uTorrent. If you do not see ads when online, you should not care (or, are running an older version of uTorrent in which scenario you will get them if you upgrade).
Go to Options > Preferences (Ctrl+P). In the “Preferences” dialog box, select Advanced in the left pane. Next, in the ‘Filter’ search box in the right pane, type in off (which is the first 3 letters of ‘offers’ indeed). This will make disappear all but some entries as follows:
…and so on.
For both ‘offers.left_rail_offer_enabled’ and ‘offers.sponsored_torrent_offer_enabled’, click to select each, and change the ‘Value’ from ‘True’ to ‘False’ by clicking the button left to ‘False’. Click OK to close the “Preferences” window.
Go to File > Exit and launch the program again. (Tip: To exit, clicking the red X in the top right corner may just minimize the client to the system tray; so, don’t do that.)
You should not see any ads anymore. What a relief!
I have tested it using uTorrent 3.4.5 (build 41372) [32-bit] in Windows 7 Professional 64 bit.
