  55 <h2><a class="anchor" href="#installing">Step One: Download and Install Tor</a></h2>
  56 <br />
  57
  58 <p>
  59 The latest stable release of Tor for MS Windows is
  60 <a href="http://tor.eff.org/dist/win32/tor-0.1.0.15-win32.exe">0.1.0.15</a>.
  61 Download it by clicking the link. You may be able to find experimental versions
  62
  63 <a href="http://tor.eff.org/dist/win32/">here</a>, if you're looking for
  64 new features and new bugs.
  65 </p>
  66
  67 <p>
  68 If you want to run Tor in the system
  69 tray and/or as a service have a look at this <a
  70 href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#Win32SystemTrayService">FAQ
  71 entry</a>. If you dont mind running in a window (so you can see its logs
  72 and errors) our Tor installer should make everything pretty simple. Below
  73 is a screenshot of the setup page (your version will probably be newer
  74 than the version printed in this screenshot):
  75 </p>
  76
  77 <img alt="tor installer splash page"
  78 src="http://tor.eff.org/img/screenshot-win32-installer-splash.png" />
  79
  80 <p>
  81 By default, Tor is not configured to run at startup.
  82 <!--We highly recommend that you enable that feature, however. -->
  83 You can enable this by checking the "Run at startup" box as shown below.
  84 Be sure to leave the other boxes checked.
  85 </p>
  86
  87 <img alt="select components to install"
  88 src="http://tor.eff.org/img/screenshot-win32-installer-components.png" />
  89
  90 <p>Once the installer is finished, it will run Tor in a window so
  91 you can see its logs and errors. (When you wish to browse anonymously,
  92 you may minimize this window, but do not close it.)
  93 </p>

  95 <img alt="tor window screenshot"
  96 src="http://tor.eff.org/img/screenshot-win32-dos-window.png" />
  97
  98 <p>Tor comes configured as a client by default. It uses a built-in
  99 default configuration file, and most people won't need to change any of
 100 the settings. Tor is now installed.

 105 <h2><a class="anchor" href="#privoxy">Step Two: Install Privoxy for Web Browsing</a></h2>
 106 <br />
 107
 108 <p>After installing Tor, you need to configure your applications to use it.
 109 </p>
 110
 111 <p>
 112 The first step is to set up web browsing. Start by installing <a
 113 href="http://www.privoxy.org/">Privoxy</a> (click on 'recent releases',
 114 then scroll down to the MS Windows installer packages). Privoxy is a filtering
 115 web proxy that integrates well with Tor. Once it's installed, it should
 116 appear in your system tray as a "P" in a circle, as pictured below:
 117 <!-- Exit from
 118 Privoxy for now by right clicking on the "P" icon and finding the exit option.-->
 119 </p>
 120
 121 <img alt="privoxy icon in the system tray"
 122 src="http://tor.eff.org/img/screenshot-win32-privoxy-icon.jpg" />
 123
 124 <p>You need to configure Privoxy to use Tor.
 125 Open Privoxy's main config file by selecting it from Start Menu|All
 126 Programs:
 127 </p>
 128
 129 <img border="1" alt="editing privoxy config"
 130 src="http://tor.eff.org/img/screenshot-win32-privoxy-config.png" />
 131
 132 <p>Add the line <br>
 133 <tt>forward-socks4a / localhost:9050 .</tt><br>
 134 to Privoxy's config file. Don't forget to add the dot at the end.
 135 The easiest way is to select the above line and copy/paste it into
 136 the file. Be sure to save.
 137 </p>
 138
 139 <img border="1" alt="privoxy points to tor"
 140 src="http://tor.eff.org/img/screenshot-win32-privoxy-edit.png" />
 141
 142 <p>Privoxy keeps a log file of everything passed through it.  In
 143 order to stop this you will need to comment out two lines by inserting a
 144 # before the line. The two lines are:<br>
 145 <tt>logfile privoxy.log</tt><br>
 146 and the line <br>
 147 <tt>jarfile jar.log</tt><br>
 148 Be sure to save.
 149 </p>
 150

 157 src="http://tor.eff.org/img/screenshot-win32-privoxy-edit-3.png" />
 158
 159 <br>
 160
 161 <p>You'll need to exit and restart Privoxy for the changes to take effect:
 162 </p>
 163 <ol>
 164 <li>Right click on the Privoxy systray icon and choose "Exit Privoxy".</li>
 165 <li>Left click on Start Menu then Programs then Privoxy.  Select the
 166 green "P" Privoxy icon.  Privoxy should appear in your system
 167 tray again.</li>
 168 </ol>

 172 <h2><a class="anchor" href="#using">Step Three: Configure your applications to use Tor</a></h2>
 173 <br />
 174
 175 <p>After installing Tor and Privoxy, you need to configure your
 176 applications to use them. The first step is to set up web browsing.</p>
 177
 178 <p>If you're using Firefox (we recommend it), check out our <a
 179 href="tor-switchproxy.html">Tor SwitchProxy howto</a> to set up
 180 a plugin that makes it easy to switch between using Tor and using a
 181 direct connection.</p>
 182
 183 <p>Otherwise, you need to manually configure your browser to HTTP proxy
 184 at localhost port 8118.
 185 (That's where Privoxy listens.)
 186 In Mozilla, this is in Edit|Preferences|Advanced|Proxies.
 187 In Opera 7.5x it's Tools|Preferences|Network|Proxy servers.
 188 In IE, it's Tools|Internet Options|Connections|LAN Settings|Advanced.
 189 You should click the "use the same proxy server for all protocols"
 190 button; but see <a
 191 href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#FtpProxy">this
 192 note</a> about Tor and ftp proxies.
 193 In IE, this looks something like:</p>
 194
 195 <img alt="Proxy settings in IE"
 196 src="http://tor.eff.org/img/screenshot-win32-ie-proxies.jpg" />
 197
 198 <p>Using privoxy is <strong>necessary</strong> because <a
 199 href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#SOCKSAndDNS">browsers
 200 leak your DNS requests when they use a SOCKS proxy directly</a>, which
 201 is bad for your anonymity. Privoxy also removes certain dangerous
 202 headers from your web requests, and blocks obnoxious ad sites like
 203 Doubleclick.</p>
 204
 205 <p>To Torify other applications that support HTTP proxies, just
 206 point them at Privoxy (that is, localhost port 8118). To use SOCKS
 207 directly (for instant messaging, Jabber, IRC, etc), you can point
 208 your application directly at Tor (localhost port 9050), but see <a
 209 href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#SOCKSAndDNS">this
 210 FAQ entry</a> for why this may be dangerous. For applications
 211 that support neither SOCKS nor HTTP, take a look at <a
 212 href="http://www.socks.permeo.com/Download/SocksCapDownload/index.asp">SocksCap</a> or
 213 <a href="http://www.freecap.ru/eng/">FreeCap</a>.
 214 (FreeCap is free software; SocksCap is proprietary.)</p>

 227 <a href="http://ipid.shat.net">ipid.shat.net</a> and
 228 <a href="http://www.showmyip.com/">showmyip.com</a>
 229 are sites that show what IP address and country you appear to be coming
 230 from.
 231 </p>
 232
 233 <p>If you don't know your current public IP address, this may not be a
 234 very useful test. To learn your IP address, go to the Start menu, click
 235 Run and enter "<tt>cmd</tt>". At the command prompt, enter "<tt>ipconfig
 236 /a</tt>". If you are behind a NAT or firewall, though, you won't be able
 237 to learn your public IP address. In this case, you should 1) configure
 238 your browser to connect directly (that is, stop using Privoxy), 2) check
 239 your IP address with one of the sites above, 3) point your browser back
 240 to Privoxy, and 4) see whether your IP address has changed.
 241 </p>
 242
 243 <p>If you have a personal firewall that limits your computer's
 244 ability to connect to itself, be sure to allow connections from
 245 your local applications to local port 8118 and port 9050. If
 246 your firewall blocks outgoing connections, punch a hole so
 247 it can connect to at least TCP ports 80 and 443, and then see <a
 248 href="http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#FirewalledClient">this
 249 FAQ entry</a>.

 261 <p>The Tor network relies on volunteers to donate bandwidth. The more
 262 people who run servers, the faster the Tor network will be. If you have
 263 at least 20 kilobytes/s each way, please help out Tor by configuring your
 264 Tor to be a server too. We have many features that make Tor servers easy
 265 and convenient, including rate limiting for bandwidth, exit policies so
 266 you can limit your exposure to abuse complaints, and support for dynamic
 267 IP addresses.</p>
 268
 269 <p>Having servers in many different places on the Internet is what
 270 makes Tor users secure. You may also get stronger anonymity yourself,
 271 since remote sites can't know whether connections originated at your
 272 computer or were relayed from others.</p>
