&gt; <i>What should the response to this sort of fraud be?</i><p>I really wouldn&#x27;t assume it was fraud. Margins aren&#x27;t that amazing on hardware, and it&#x27;s very possible that Microsoft has more of an interest in having your father on Win 10 than selling him a new laptop. In fact, Microsoft&#x27;s hardware business is supposedly just to make sure that flagship Windows machines exist, not to make Microsoft the premier vendor or have the largest market share.<p>This false negative was probably A) a bug, B) a design flaw in the installer that told you whether the PC could run Win 10, or C) Microsoft covering their asses.<p>In the past, Microsoft caught tons of flak for driver issues when people upgraded to Windows Vista. They&#x27;ve probably learned their lesson on that one.
