Screenshots of a near final copy of Windows 8 beta leaked to the Internet over the weekend.
The screenshots demonstrate a number of setup customisations available in the beta version of Windows 8. Theme colors for the Windows 8 Start Screen experience can be selected prior to install and it appears most of the colors on the slider are dark blue, pink, green and purple variants.
