"In the past, early adopters of new Windows versions have had some small hurdles to overcome. Such hurdles may be software incompatibility, or lack of driver support. These sorts of things are almost expected with each new Windows launch. But what would you do if you bought Windows Vista and your product key didn’t work? What if Microsoft had no solution and was unwilling to issue you a new key? Many (if not all) users who took advantage of Microsoft’s Vista Family Discount have been issued invalid installation keys and cannot install Windows Vista Home Premium. Microsoft confirms that the keys are indeed valid, but not for Windows Vista. The CSR I spoke with was unable to tell what the key was for, but it did appear to be a valid key, for something."Well, they say that most people come from a dysfunctional family, so maybe this is Microsoft's clever way of being, you know, culturally relevant. ;-) All kidding aside, this is utterly ridiculous - the discount was already somewhat de-valued by the need to purchase Ultimate, and now it's not working at all? Didn't they test this before rolling it out?
