We now have volume-licensed versions of Windows Vista Enterprise available for installation over the network or on DVD loan from the Helpdesk. Both 32-bit (x86) and 64-bit (x64) versions are available, and they include Service Pack 1.
Instructions for installing and activating Windows Vista are available from our Windows installation FAQ page. If you wish to install Vista on a machine that supports booting via the network interface (PXE), we strongly recommend doing a network install.
