Internet Explorer 9 will not be broadly rolled out on Windows Update until the
end of June. We do this because we have hundreds of millions of business
customers that rely on Internet Explorer and require an appropriate window of
time to plan and test their deployments. We also have a responsibility, as the
most popular browser on the planet, to ensure that IE9 is introduced in a
timeline that allows web site developers to have the chance to ensure their site
is 100% ready.
