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. Win8china posted the screenshots over the weekend.
