Microsoft has completed the entire process of upgrading Windows Live Hotmail to Wave 4. As a result, over 350 million users, 1.3 billion inboxes in more than 220 countries around the world have now been upgraded to Windows Live Wave 4.

Now, everyone can take advantage of a faster Hotmail experience with great new features like one-click filters, Sweep, Active Views and more.

“Here at Hotmail, we’ve had quite a busy week! All of our customers are now upgraded. The majority of you got the new Hotmail just this past week, as we completed the rollout to over 350 million people in more than 220 countries around the world. Now, everyone can take advantage of a faster Hotmail experience with great new features like one-click filters, Sweep, Active Views and more.

We hope you like the new Hotmail. We want to hear from you, whether you like it or whether you’re having any issues or problems (or just found things you don’t like). You can leave comments in this blog, use our support forums or click the feedback link right in Hotmail (you can find it in the lower right corner of the page).

We’ve already gotten lots of feedback, and we’ve already made some changes based on the feedback we’ve received – for instance, we no longer sign you into Messenger by default,” says Mike Schackwitz.

The new Windows Live Hotmail comes with smart tools to help you save time and get more done. You can easily cut through inbox clutter, filter junk automatically, and work with Word, Excel, and PowerPoint files right from your email for free—even if you don’t have Microsoft Office installed on your PC!
