In a corporate environment, an administrator would extract the ISO to a network share, then use the Windows Automated Installation Kit (WAIK) to create an answer file ( autounattend.xml ). This XML file could pre-answer every setup question: disk partitioning, product key, time zone, local administrator password, and even which applications to install. The ISO became the source for a PXE boot server, allowing hundreds of desktops to install Windows 7 Pro simultaneously overnight.
