Windows 10 Technical Preview is here, free to try out in Microsoft's Windows Insider Program. Whether or not you want to kick the tires on the new OS--make a backup first and run it in a separate partition or virtual machine--you can learn more about Windows 10 from Microsoft's guide to the technical preview.
It's a free PDF that highlights how to do things like use the task view, view multiple desktops, access quick links and frequently used apps, and, yes, go straight to the desktop with the new start menu instead of the much-hated start screen.
In other words, it's also a quick guide to what's new in Windows 10, expected next year. Will you be installing it?
