Diskeeper 10 (a beta version) is now available for Windows Vista builds 5381 and 5384 (aka Vista Beta 2). Beta 2 will be the first release available to the general public to test out. For MSDN/TechNet subscribers, you've likely already installed the latest OS. For the rest of us, you can sign up at Microsoft here (https://www.microsoft.com/betaexperience/default.aspx) to get access to it in the coming weeks as part of the Customer Preview Program.
