It's been a little over a year since we released IE7 on Windows XP and for Windows Vista, so I thought it would be worthwhile to talk about where we are after the year.
According to internal Microsoft research based on data from Visual Sciences Corporation, there are over 300 million users are experiencing the web with IE7. This makes IE7 the second most popular browser after IE6. IE7 is already #1 in the US and UK, and we expect IE7 to surpass IE6 worldwide shortly.
Perhaps more important than the overall numbers is the positive impact IE7 has made for our users. As you know, we focused a lot on improving security in IE7. We believe IE 7 is the safest Microsoft browser released to date. According to a vulnerability report published today, IE7 has fewer vulnerabilities than previous versions of IE over the same time period. What's more, the report showed that IE7 had both fewer fixed and unfixed vulnerabilities in the first year than the other browsers we compared.
