Valid software from a legitimate press (factory, authorized) NEW Sealed in the Origin facility packaging. Good as Gold. The included Key and slipcase also authentic, NEW and pristine. That is saying something for a Operating System release well past its "fresh age". It was is good NOS [New Old-Stock]. Key is a real printed item from MS. It shipped safely to me across many states. Great vendor is ForVac23. I looked for months to find this particular software, they delivered in heaps of goodness !
