Just confirmed on The Windows Blog, the much anticipated Live Essentials 2011 beta (or wave 4) will be released to the public tomorrow. Just to re-iterate, XP users are out of luck, the new version will only be available for Windows Vista and Windows 7 users. Time to upgrade..
The Photo Fuse feature is definitely one to look out for, new to this version of Windows Live Photo Gallery it allows you to pick the best elements from multiple photos and create one perfect photo.
