All Dell PCs bought after 29 June, 2009 are eligible for a complimentary Windows 7 upgrade, according to a recent announcement by the floundering PC maker. But Dell forgot to mention that in case of PCs bought from brick-and-mortar stores, the date of purchase, in context of this offer, is that date when the third-party retailer bought the PC from Dell. As this date invariably precedes the actual date of purchase – the date on which the PC is bought by the customer, it can potentially render many customers ineligible for the free Windows 7 upgrade. Dell is avowedly aware of the problem and currently working toward a solution.
