If you ever stumble upon an old ISO with that name, fire up a virtual machine. Look past the clunky fonts and the unpolished icons. You aren't looking at a beta. You are looking at Microsoft holding its breath, hoping that this time, it would get the love that Vista never did.
Just two years prior, the world had met Windows Vista. It was beautiful, but it was heavy. It demanded hardware that didn't exist yet, nagged users with User Account Control (UAC), and ran slower than molasses on the netbooks that were suddenly flooding the market.
