uTorrent Updates
From KlavoWiki
For some reason when uTorrent auto updates it does not replace the main executable file with the new version.
Replace the latest update file in this path
%APPDATA%\uTorrent\updates
with
%APPDATA%\uTorrent\uTorrent.exe
Example
copy %APPDATA%\uTorrent\updates\3.5.0_44294.exe %APPDATA%\uTorrent\uTorrent.exe
