Internet Explorer 10 introduces a new privacy feature that can send a Do Not Track request to the websites you visit. You can turn this request on or off to express your preference about tracking at any time.
When you visit a website in any browser, you automatically share information with that site, such as cookies, your IP address, and other standard computer information. If the site contains content provided by a third–party website (for example a map, advertisement, or web measurement tools such as a web beacon or scripts) some information about your browser might be automatically sent to the content provider. This type of arrangement has several benefits: For example, you can access third-party content conveniently, the advertising that you see might be more relevant and interesting to you, and the presence of advertising on a site you're visiting might let the site provide access to premium content at no charge. There can, however, be an impact to your privacy as a result, because it is possible for the content providers to track you across multiple sites where they might be providing content.
When the Do Not Track feature in Internet Explorer is turned on, Internet Explorer will send a Do Not Track request to the sites you visit and to the third parties whose content is hosted on those sites. Sites might respect the signal or might continue to engage in activities you might view as tracking even though you have expressed this preference, depending on the sites' privacy practices.
To turn the Do Not Track request on or off
Open Internet Explorer for the desktop, tap or click Tools, then tap or click Internet options.
On the Advanced tab, under Settings, under Security, do one of the following:
