Neowin.net reports that OSBetas have got the nitty gritty on the lastest leak from Microsoft. Windows Preinstallation Environment (WinPE) is a minimal operating system, based on the Windows XP kernel and contains the minimal functionality you need to run and automate Windows Setup.
WinPE lets you create (diskpart.exe) and format (format.com) disk partitions, and gives you access to both NTFS file system partitions (with some constraints) and your internal network. The environment supports all mass storage devices that use Windows 2000 or Windows XP drivers, and you can incorporate additional drivers as new devices become available. Windows PE RTM @ Neowin.net
