Some Web site services may not work properly after you upgrade to any of the versions of Internet Explorer listed at the beginning of this article. The Web site may suggest that you need to enable cookies or upgrade your browser to one that supports Java, frames, or other technology that is supported by Internet Explorer 6.

For example, when you attempt to log on to, or use, a secure banking Web site, you may be prompted to upgrade to a compatible browser or a different version of the same browser.

Internet Explorer 6 implements advanced cookie filtering based on the Platform for Privacy Preferences (P3P) specification. The cookie settings that are configured on the Security tab of Internet Options in Internet Explorer 4 and Internet Explorer 5 (or on the Advanced tab in Internet Explorer 3) are removed when you upgrade to Internet Explorer 6. By default, Internet Explorer 6 sets your privacy preferences to Medium for the Internet zone. Unsatisfactory cookies are blocked at the Medium privacy level, and this can prevent some Web sites from creating or reading these types of cookies on your computer. If the Web site requires unsatisfactory cookies to work properly, you may experience problems gaining access to some parts of the Web site or using some of its services.

NOTE: This behavior can also occur if you attempt to access a Web site's services in a third-party context.
