Microsoft has quietly updated its Account page and they have done away with the old blue page in favor of a clean and simple layout. While it does not look like there are any new features, the updated UI does make it easier to find the content you are looking for.
You can check out the new page by going to account.live.com and, after logging in, you will see the new layout shown at the top of this page.
Aside from the visual update, there"s not much else to point out but if you do find something lurking in the details, make sure to send us a tip and we will update this post.
Thanks for the tip Maxime!
