Starting July 1st, 2009, when you launch Windows Live Movie Maker Beta you will be prompted to implement a software update which will extend the beta. You can download the software update here to continue to use the software without any interruption. If you choose not to install the software update, you will be unable to continue to use the Windows Live Movie Maker Beta.
The folks on the Windows Live Movie Maker Team are hard at work on “V1” which should be out sometime this year. For more information on the future of Windows Live Movie Maker, see this excellent blog post by Lead Program Manager Mike Torres from the Windows Live Team Blog.
I’m pretty excited for what they have in store for Windows Live Movie Maker!
