<h1>Running the <a href="http://tor.eff.org/">Tor</a> client on MS Windows</h1>

<b>Note that these are the installation instructions for running a Tor
client on MS Windows (98, 98SE, NT4, 2000, XP, Server).

<h2><a class="anchor" href="#installing">Step One: Download and Install Tor</a></h2>
<br />
<p>
The install for MS Windows bundles <a href="http://tor.eff.org/">Tor</a>,
<a href="http://www.freehaven.net/~edmanm/torcp/">TorCP</a>
(a Tor controller that lets you monitor and control Tor), and <a
href="http://www.privoxy.org">Privoxy</a> (a filtering web proxy) into
one package, with the three applications pre-configured to work together.
The latest stable version provides
<a href="http://www.freehaven.net/~edmanm/torcp/download/tor-0.1.0.16-torcp-0.0.4-bundle.exe">Tor 0.1.0.16, TorCP 0.0.4, and Privoxy 3.0.3</a>.
Download it by clicking the link.
<!--
The latest experimental version provides
<a href="http://www.freehaven.net/~edmanm/torcp/download/tor-0.1.1.10-torcp-0.0.4-bundle-2.exe">Tor 0.1.1.10-alpha, TorCP 0.0.4, and Privoxy 3.0.3</a>.
Download it by clicking the link.
-->
</p>
<p>
If you prefer the experimental (unstable) versions of Tor, you can try <a
href="http://freehaven.net/~edmanm/torcp/download/tor-0.1.1.12-torcp-0.0.4-bundle.exe">the experimental bundle that includes Tor 0.1.1.12-alpha</a>.
<b>You need the experimental bundle if you want to run a Tor server
and configure it via TorCP, or if you want to offer a hidden service.</b>
</p>
<p>If the bundles don't work for you, you can download Tor by itself
from the <a href="http://tor.eff.org/download">download page</a>, and then <a
href="http://tor.eff.org/cvs/tor/doc/tor-doc-unix.html#privoxy">install
and configure Privoxy on your own</a>.
</p>
<img alt="tor installer splash page"
src="http://tor.eff.org/img/screenshot-win32-installer-splash.png" />
<p>If you have previously installed Tor, TorCP, or Privoxy
you can deselect whichever components you do not need to install
in the dialog shown below.
</p>
<img alt="select components to install"
src="http://tor.eff.org/img/screenshot-win32-installer-components.png" />
<p>After you have completed the installer, the components
you selected will automatically be started for you.
</p>
<!--
<p>Tor comes configured as a client by default. It uses a built-in
default configuration file, and most people won't need to change any of
the settings. Tor is now installed.
</p>

<a id="using"></a>
<h2><a class="anchor" href="#using">Step Two: Configure your applications to use Tor</a></h2>
<br />
<p>After installing Tor and Privoxy, you need to configure your
applications to use them. The first step is to set up web browsing.</p>
<p>If you're using Firefox (we recommend it), check out our <a
href="tor-switchproxy.html">Tor SwitchProxy howto</a> to set up
a plugin that makes it easy to switch between using Tor and using a
direct connection.</p>
<p>Otherwise, you need to manually configure your browser to HTTP proxy
at localhost port 8118.
(That's where Privoxy listens.)
In Mozilla, this is in Edit|Preferences|Advanced|Proxies.
In Opera 7.5x it's Tools|Preferences|Network|Proxy servers.
In IE, it's Tools|Internet Options|Connections|LAN Settings|Advanced.
You should click the "use the same proxy server for all protocols"
button; but see <a
href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#FtpProxy">this
note</a> about Tor and ftp proxies.
In IE, this looks something like:</p>
<img alt="Proxy settings in IE"
src="http://tor.eff.org/img/screenshot-win32-ie-proxies.jpg" />
<p>Using Privoxy is <strong>necessary</strong> because <a
href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#SOCKSAndDNS">browsers
leak your DNS requests when they use a SOCKS proxy directly</a>, which
is bad for your anonymity. Privoxy also removes certain dangerous
headers from your web requests, and blocks obnoxious ad sites like
Doubleclick.</p>
<p>To Torify other applications that support HTTP proxies, just
point them at Privoxy (that is, localhost port 8118). To use SOCKS
directly (for instant messaging, Jabber, IRC, etc), you can point
your application directly at Tor (localhost port 9050), but see <a
href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#SOCKSAndDNS">this
FAQ entry</a> for why this may be dangerous. For applications
that support neither SOCKS nor HTTP, take a look at <a
href="http://www.socks.permeo.com/Download/SocksCapDownload/index.asp">SocksCap</a> or
<a href="http://www.freecap.ru/eng/">FreeCap</a>.
(FreeCap is free software; SocksCap is proprietary.)</p>
<p>For information on how to Torify other applications, check out the
<a href="http://wiki.noreply.org/wiki/TheOnionRouter/TorifyHOWTO">Torify
HOWTO</a>.

<h2><a class="anchor" href="#verify">Step Three: Make sure it's working</a></h2>
<br />
<p>
Check to see that Privoxy and TorCP are running and that TorCP has
successfully started Tor. Privoxy's icon is a green circle with a "P"
in it, and TorCP uses a fat grey onion with a green checkmark in your
system notification area, as shown below:
</p>
<img alt="TorCP Tray Icon"
src="http://tor.eff.org/img/screenshot-win32-torcp.png">
<p>
Next, you should try using your browser with Tor and make sure
that your IP address is being anonymized.
<a href="http://ipid.shat.net">ipid.shat.net</a> and
<a href="http://www.showmyip.com/">showmyip.com</a>
are sites that show what IP address and country you appear to be coming
from. Click on one of them and see what it says.
</p>
<p>If you don't know your current public IP address, this may not be a
very useful test. To learn your IP address, go to the Start menu, click
Run and enter "<tt>cmd</tt>". At the command prompt, enter "<tt>ipconfig
/a</tt>". If you are behind a NAT or firewall, though, you won't be able
to learn your public IP address. In this case, you should 1) configure
your browser to connect directly (that is, stop using Privoxy), 2) check
your IP address with one of the sites above, 3) point your browser back
to Privoxy, and 4) see whether your IP address has changed.
</p>
<p>If you have a personal firewall that limits your computer's
ability to connect to itself, be sure to allow connections from
your local applications to local port 8118 and port 9050. If
your firewall blocks outgoing connections, punch a hole so
it can connect to at least TCP ports 80 and 443, and then see <a
href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#FirewalledClient">this
FAQ entry</a>.
</p>
<p>If it's still not working, look at <a
href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#ItDoesntWork">this
FAQ entry</a> for hints.</p>

<a id="server"></a>
<h2><a class="anchor" href="#server">Step Four: Configure it as a server</a></h2>
<br />
<p>The Tor network relies on volunteers to donate bandwidth. The more
people who run servers, the faster the Tor network will be. If you have
at least 20 kilobytes/s each way, please help out Tor by configuring your
Tor to be a server too. We have many features that make Tor servers easy
and convenient, including rate limiting for bandwidth, exit policies so
you can limit your exposure to abuse complaints, and support for dynamic
IP addresses.</p>
<p>Having servers in many different places on the Internet is what
makes Tor users secure. You may also get stronger anonymity yourself,
since remote sites can't know whether connections originated at your
computer or were relayed from others.</p>
