Microsoft Internet Explorer [ all versions ]

Modifying the registry can cause serious problems that may require you to reinstall your operating system. We cannot guarantee that problems resulting from modifications to the registry can be solved. Use the information provided at your own risk.

Whenever a web browser is used to connect to a remote web server it includes a User Agent string that contains details about browser and operating system. This tweak allows you to add or remove additional information from this string.

A standard user agent string would look similar to:

Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)

Which means Internet Explorer 5.5 running on Windows 2000.

When a customised user agent string is used it may contain additional information set by the company that created the branded version of the browser. For example a branded version from an ISP may look like:

Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; Your_ISP_Name)

This information sent to the remote web server may be stored in the log files and possibly used to track branded versions of a web browser.

To Change This Information :

Open your registry and find the key below.

Each value name listed in this key will be sent to the remote web server as an additional entry in the user agent string. To remove any additional information delete all the entries within the [Post Platform] key. To add additional entries create a string value and name it the string you want to be sent.

Restart Internet Explorer for the changes to take effect.

Download - this example registry file that adds 'http://www.jaysafe.co.uk/' to the user agent.
