Vista from build 5112 until 5231 does require activation. On build 5112 it is done by Start>Run>Licenseui.exe and on 5219 and 5231 it is done by Start>Run>SLUI.exe. That will bring up the activation for Vista.Tyler1989 said:Well Longhorn (note that is is not called Vista) Server Beta 1 currently out performs Windows Server 2003 on the same hardware.
I'd also like to say Vista does require activation.
