µTorrent Installation, Setup and Optimization
µTorrent is a powerful and efficient BitTorrent client for Windows. µTorrent has most of the features common to other BitTorrent clients, including bandwidth prioritization, scheduling, RSS auto-downloading, and Distributed Hash Table (DHT). Additionally, µTorrent supports the protocol encryption joint specification and Peer Exchange (PEX). Unlike many torrent clients, µTorrent does not tax valuable system resources; typically using less than 6MB of memory.
This Guide will cover the "Installation", "Setup" and "Optimization" of the µTorrent BitTorent Client. I have tried to make this guide clear, concise and complete. To this end, most settings are color coded and highlighted in the illustrations; a brief explanation is also included. Some calculations are needed, but nothing beyond simple arithmetic. My hope is that everyone, to some degree, will find this guide helpful.
To make the separate sections stand out, each will be preceded by the µTorrent Icon

Download and Install µTorrent
Download the latest stable version of µTorrent. On the Download Page, are two available stable versions of µTorrent. The "Installer Version" and a "Stand Alone Version". The only difference between the two is that the "Installer Version" will create "Start Menu" and "Desktop" shortcuts during the installation process; however, on first run, the "Stand Alone Version" will ask if you would like to make shortcuts on your start menu and desktop. This section will cover the "Installer Version" of µTorrent. (Click the thumbnails to enlarge)
"Double Click" or "Run" the µTorrent installation executable
Choose a language and Click "OK"
Click "Next" to continue.
"Browse..." to a "Destination Folder", or accept the default, then Click "Next".
Choose a "Start" menu folder, or Choose "Do not create shortcuts", then Click "Install"
Wait for µTorrent to be installed.
Click "Finish" to close the Wizard.
When given the option to add "Shortcuts"; choose as desired.
When prompted to make µTorrent the default application for .torrent files,
Click "Yes" and torrent files (.torrent) will be automatically opened with µTorrent.
When µTorrent is "Opened" for the first time, the "Speed Guide" is displayed.
The Speed Guide will help you set your network for optimal speeds.
After the initial "Installation Start", when "Run", the µTorrent icon will appear at bottom right of the screen,
in the Windows System Tray. Double Click the µTorrent Icon
to open the GUI.Initial Setup
After installation, µTorrent will open to the "Speed Guide" Window. The µTorrent “Speed Guide” will help you setup the
network settings, for optimal speed. The "Speed Guide" can be accessed at any time by navigating to
µTorrent > Options > Speed Guide (Ctrl + G)
A) Speed test
The settings in µTorrent are directly proportional to the Maximum Upload Rate. For the initial setup of µTorrent,
you can use the "Advertised" (claimed) Max Upload Rate from the Internet Service Provider (ISP),but by doing a speed test you can more accurately judge your current line throughput or internet connection speed.It is advisable to do a speed test when prompted.
1) Stop all internet traffic before proceeding with the test.
2) Visit one of the numerous speed testing sites such as DSL Reports, Speakeasy or Speedtest.net.
3) Perform the test several times. Select a good median result (neither the highest nor the lowest).
4) The value needed to proceed with the initial settings is the Max Upload Rate, expressed in kilo bits per second (kb/s)
not kilo Bytes per second (kB/s). [ 1 kB/s = 8 kb/s ]
Connection Type and Speed Setting1) Expand the "Connection Type" Drop Down Menu and using the "Advertised" (claimed), or Tested Maximum Upload Rate.Select the listing closest to your Upload Rate in kilo bits per second, rounding down as necessary.
2) Speed tests may not be 100% accurate due to factors outside your control, if the closest speed option
is only slightly higher than your Maximum Upload Rate (within 10%), it's generally safe to select that option.
3) You will notice that the "Affected Settings" have adjusted to match the selected speed.
Higher settings will not yield better speeds, and may in fact make speeds worse.
C) Port Check and Forwarding
To get the most from your given network connection it is vital you have an open port and that it is properly forwarded through the Router and/or Modem. Software ports are numbered connections that a computer uses to sort network traffic.A port may support incoming traffic, outgoing traffic, or both.
When a computer on the internet sends data to the external IP Address of your router, the router needs to know what to do with the data.Port Forwarding tells the router, to which computer, on the local area network (LAN) to send the data.When you have port forwarding rules set up, the router takes the data from the external IP Address / port number and sends that data to an internal IP Address / port number. Port Forwarding rules are created per port, so a rule set up for port 6881 will only work for port 6881,and therefore a port can only be used by one program at a time!
Pick any random port between 49152 and 65535, the "Unassigned" port range and enter that port number in the "Current Port" field. Click the "Test if port is forwarded properly" button to check the port you have chosen. The Default Browser will open and test the chosen port's mapping.
If the µTorrent Port Checker displays this message, congratulations your port is open and accepting connections.
If the µTorrent Port Checker displays this message, the port is not "Open", go to Portforward.com and allow the site to guide you through the forwarding process. You will need to know the Router and/or Modem manufacturer, Model and the Username and Password; check the manual if the passwords suggested by Portforward.com don’t work.
D) Protocol Encryption
Some Internet Service Providers (ISPs) are actively interfering with P2P activities to reduce their bandwidth requirements.This causes the download speeds of file sharing programs, to become slow. To avoid this, µTorrent and other clients have introduced Protocol Encryption to prevent ISPs from identifying BitTorrent traffic.
Optimizing the Internet Connection
Tweaking the Network Settings
“Tweaking” the TCP stack is necessary if you wish to fully utilize the available bandwidth of your connection.
You can do an “On-Line” tweak test at DSL Reports or use a program like TCP Optimizer.
TCP Optimizer is a free, easy, "No Install" program that provides an intuitive interface for tuning and optimizing your Internet connection.
TCP Optimizer - Download
TCP Optimizer - “On-Line” Documentation
1 ) Select the Maximum "Advertised" (claimed), or Maximum Tested Download Rate, from the "Connection Speed" slider bar.
(The maximum available bandwidth, in kilobits per second [kb/s]).
2 ) Choose your "Network Adapter", or check to "Modify All Network Adapters".
3 ) Check "Optimal settings"
4 ) Click "Apply changes", and reboot when prompted by the program.
The Event ID 4226 Patch
Windows Vista, Windows
SP2 and Windows 2003 Server SP1 limit the maximum concurrent half-open connections (SYN) to a maximum of 10 (the previous limit was over 65,000). The drawback to this connection limit is that network intensive applications can be slowed, including Peer-to-Peer (P2P) clients like µTorrent.
To change the limit on maximum concurrent half-open connections, effectively editing the TCPIP.SYS file, use the Event ID 4226 Patch.
A complete guide can be found here: Windows
SP2 and the Event ID 4226 PatchWindows
SP2 and Windows 2003 Server SP1 DownloadWindows Vista Download
Once the TCPIP.SYS file, has been patched, open µTorrent and navigate to:
Options > Preferences (Ctrl+P) > Click "Advanced" > Click “net.max_halfopen” > Enter "50" in the "Value" Field > Click "Set"
Do not change the “net.max_halfopen” value, without first patching the TCPIP.SYS file, using the Event ID 4226 Patch.
To truly optimize µTorrent, set the limit to 50 and use µTorrent normally; periodically check the Windows Event Viewer for Event ID 4226 errors;
if these errors are found, raise the limit by 50, continuing this process, until these errors are no longer logged.
To access the Windows Event Viewer, navigate to: “Start” > "Run" > Enter " eventvwr.msc " > Click "Ok"
µTorrent “Preferences”
This section provides descriptions of options available in the µTorrent Preferences dialog. Nearly all of µTorrent's internal settings can be configured here.
This section will make recommendations for µTorrent “Preferences”. Many settings deal simply with usability issues, while others can greatly affect the program’s ability to transfer files, and the speed at which µTorrent, downloads.
To make this guide easier to use, where applicable, the recommended settings will have a green checkmark in the illustrations.When a calculation or other options are available, they will be explained below the relevant “Preferences” image.
