IE7 is already available as an official beta and most people agree on that the new browser is a big step in the right direction for Microsoft. Even if IE7 will not gain its full functionality, although close to it, before Windows Vista arrives Microsoft seems very keen on spreading the new browser also among the Windows XP users. Microsoft has namely announced it will add IE7 as an “important update” with Windows Update when the final version is released later this year. According to Microsoft it is the browser’s improved security functions that makes it defendable to add IE7 as an important update. You will still have the option to install the new browser, or not.
