In our conversations with Microsoft, they believe this policy applies to all systems that provide recovery discs that seek authentication from the motherboard EEPROM... Acer, Alienware, Compaq, Dell, eMachines, HP, Sony, Systemax, and so on.
When you read the fine print, you find you were informed that the operating system is provided only for that "system".
Dell and HP both sell full versions of Windows as an alternative, and the purchase agreements give the details.
A review of the prices of these "systems" pretty much indicate you are not paying much for the operating system, and Microsoft has gone to a great deal of work to assure that piracy cannot take place.
Their weak link was in refurbished machines. Even store or on-line refurbs no longer provide machines that can be installed with another recovery disc.
It may not seem right, but there is disclosure. The problem comes when you have a crummy computer, where failure rates exceed 60 percent on some eMachines models. Can't blame that on Microsoft.
