Some companies track Web site statistics, such as how many times their content is accessed and what type of Web browsers are being used. You can track the use of your customized version of Windows® Internet Explorer® by using a user agent string, which is sent in the header of every HTTP request so that a site's Web server can detect what type of browser is being used.

In this page in the Internet Explorer Customization Wizard 8, you can customize the user agent string by adding characters to the end of the string. Customizing the user agent string is optional, but if you decide to do this, be aware that other companies that track site statistics will see the customized string.

	Notes
	For Internet Explorer 7, the value MSIE 7.0 (with a space) is used to identify browser type. For Internet Explorer 8, the value MSIE 8.0 (with a space) is used to identify browser type. The recommended maximum size for the user agent string is 200 characters.
