We are about to purchase an enterprise license from microsoft which entitles us to enterprise windows 7. We have over 600 machines country-wide with windows 7 professional installed. Is there a method of upgrading all windows 7 pcs to enterprise? Can it be done via a GPO without any user input?
Windows 7 Enterprise can only be reinstalled or upgraded from another Enterprise edition (i.e. Win7 Ent or Vista Ent)...
Windows 7 Pro can be upgraded in place to Ultimate (which has the same features as Enterprise).
Windows 7 Enterprise must be a fresh install if attempting to go from Windows 7 Pro; there is no upgrade path.
