The Tor Browser Bundle is available for download on a multitude of sites. However, it is highly recommended that you only obtain the package files from torproject.org, the official home of Tor. Windows users can choose from over a dozen languages, ranging from English to Vietnamese.
To begin the download process, navigate your current browser to https://www.torproject.org/projects/torbrowser.html.en. Next, scroll down until you find your desired option in the Language column, clicking on its corresponding 32-bit link found under the Microsoft Windows header and circled in the example above. Once the download is completed, locate the self-extracting .exe file (tor-browser-x.xx_language.exe) and launch it. A folder will now be created at your specified location, containing all package files and named Tor Browser.
To ensure that you have received the intended package, and were not duped by a hacker, you may want to verify the signature on your downloaded package prior to utilizing it. To do so you'll need to first install GnuPG and download the package's associated .asc file, available on the Tor Browser Bundle download page. Visit Tor's signature verification instructions page for further details.
