So in your mind how long does that mean MS should support that version of Windows you bought? Seems like you're arguing MS should switch to a subscription-based model for Windows like most "continuously updated" software has because otherwise I don't see how you can expect them to provide you with free updates perpetually year-after-year after you paid them exactly once for software delivered as-is.
