You don't have to wait for Windows 8
Why wait until Windows 8 is released before you sample the look and feel of the next version of Windows? WindowsX has released not one, but two tools that can revamp the Windows interface and give you a fresh new look that matches Windows 8’s look and feel quite closely, right down to Metro-like functionality.
Windows 7 users should take a look at the Windows 8 UX Pack, recently updated to version 3.0, which contains everything you need. Vista, XP and Windows Server users will need a bit more help in the form of the Windows 8 Transformation Pack.
The Transformation Pack works by roping in various third-party tools that help give older versions of Windows, particularly XP, updated features like an Aero-like semi-translucent background, new icons and a revamped Start menu. It, along with the Windows 8 UX Pack, then skins the interface to provide you with the look and feel of Windows 8’s Metro interface.
Sadly, that’s all there is; XP users get the most benefit from this approach, as you’re given features that close the gap between your ancient OS and its successors Windows 7 and Vista. There is some good news if you’re a Windows 7 user, however, and that’s in the form of a free tool called Pulmon, currently in Beta. This does more than simply provide the simplified Metro-like interface, it also allows you to experiment with some gadgets created to take advantage of the new approach utilized in Windows 8, allowing you to get a greater feel for what’s coming soon.
