Recognizing the inconvenience and nightmare that upgrading dozens,
hundreds, or even thousands of activated machines will cause,
Microsoft will be offering volume licensing. Window XP volume license
product keys (VLK's) will not require activation, hardware checking,
or limitations on using imaging for installation (Ghost, Drive Image,
etc.). Corporate IS departments will be able to create a standard
installation and deploy it using imaging, or remote installation,
without requiring activation."
