Dell has decided to abandon a lot of its customer base with its decision to not support the Win10 Anniversary update (1607). I have an XPS 8300 that is not supported. I suppose the only recourse for those of us who are to be treated this way is to abandon Dell as a supplier. No issue with my HP laptops (with older technology) or with my HP desktop.
Thanks, Dell. It is not exactly what one might expect from a business that is customer-focused.
