Since its availability on March 14th, IE9 has been available for manual
download and we are pleased by the early and continued enthusiasm for IE9.
We are seeing not only strong customer and business demand, but some of the
highest web and application compatibility rates in IE history, not to mention
all the sites that are taking advantage of HTML5 and IE9’s Windows 7
integration. On March 28th, we began to upgrade existing IE9 Beta and RC users through
On April 18th, a little over a month after the final release of
IE9, we will be ready to start the rollout of IE9 to our Windows 7 and Windows
Vista customers. We will offer IE9 to customers via a gradual rollout and
expect the rollout to be largely complete by the end of June. Similar to
our approach for IE8, we will use Windows Update to
deliver IE9 to users. IE 9 will not install automatically on
machines. Users will have to agree to install IE 9.
For our business customers who require time to plan and test their
deployments, we will make IE9 available on Windows Server Update Services
(WSUS) in June. WSUS allows use of management tools that
make it easy for IT professionals to deploy IE9 in their environments in an
automated fashion and at their own pace. We would also like to remind our
business customers who do not rely on WSUS they have the option to use the IE9 Blocker Toolkit to prevent IE9 rollout via
Windows Update until they are ready.
