Although this is not the right time to talk about Windows 8, Microsoft has already confirmed that Windows 8 work is under progress.
As you one can predict, there is no information available on Windows 8 including GUI till date. But Windows lovers have already started dreaming of
Windows 8. A deviantart user has come up with a Windows 8 transformation pack that helps you turn around Windows Vista into Windows 8.
You will find nice Windows 8 wallpapers and Windows 8 logon screen background in this pack.

Artist's Comments
Windows 8 Professional Edition RC1_xbuild7.0.1128
Changes your Windows Vista into Windows 8 Pro.
As you all know Windows 8 not yet been made.

But Windows 8 provides lots of new features along with a newly designed interface. It looks very similar to Windows Vista and Windows 7(Great combination) but there
are many GUI changes like redesigned taskbar, Explorer, new boot screen and login screen, etc.
