Do you wish to go back to the days of µTorrent before it had ads? This is still possible, if you change some settings within the program.
Go to Options, Preferences, and select Advanced
Search for the following attributes and set each value as false by double clicking on the value:
bt.enable_pulse
gui.show_notorrents_node
gui.show_plus_upsell
offers.content_offer_autoexec
offers.left_rail_offer_enabled
offers.sponsored_torrent_offer_enabled
You can type just a partial like pulse
for bt.enable_pulse
Double-click on the attribute and the value will switch.
An asterisk next to the value (e.g. *false) means the setting is not the default for µTorrent in the current version
Keep going through all the settings you need to set as false/
After you are done with all the attributes, click Apply then click OK
