The Windows 7 + Windows Live connection is looking more exciting and will “complete the Windows Experience” together. Microsoft has learned that many end-user experiences need to be updated more frequently. Instead of waiting for the next Windows release, we began delivering updated versions of the Windows Live applications to improve those end-user experiences.
While this was a great way to improve the Windows experience for users, many of these updates in Windows Live Wave 2 seemed duplicative of applications already in Windows.
To address this, Microsoft will now only ship these applications (which include Windows Live Mail, Windows Live Messenger, Windows Live Photo Gallery, Windows Live Writer and now Windows Live Movie Maker) as part of the Windows Live Essentials Suite, writes Brandon.
