Using a network share as an installation source for Win7

(When Win 7 needs to be installed on 100 PC's)

As an alternative to DVD-ROMs or USB storage devices, you can host the Windows 7 installation files on a network share. To do this, you need to copy the contents of the Windows 7 installation media to a network share accessible to the clients on which you want to deploy Windows 7. To access a network share as an installation source from the client computer, you need to boot the client computer into the Windows Preintallation Environment (Windows PE) environment. The Windows PE environment is a minimally featured operating system that allows you to access diagnostic and maintenance tools as well as access network drives. Once you have successfully booted into the Windows PE environment, you can connect to the network share and begin the installation by running Setup.exe.
