If you are a "cool user", then buy a key for 2-3 and you will be happy. If you are just a person, buy a box with a flash drive and you will be happy. Different pros: Product in a box with a flash drive. And now about the main thing: it did everything by itself, it was only necessary to send it into the hole (a USB flash drive with Win10 into the USB port). Installed on a "pristine" device (monoblock with DOS), the skill is just a user. If I had taken not this option with a flash drive, but with an electronic key, I would have danced with a tambourine, and then I would have to bow to outside "experts". And so I got it, put it in and she (Windows) did everything herself. Different cons: PRICE, PRICE and again price. Winda agreed with the toad and choked, choked me. But I defeated them and bought a box.
