Used it to upgrade win11 home, worked just fine

Una locura para el precio que tiene muy recomendable

Worked perfectly. No complaints.

Instalación exitosa, sin inconvenientes, según el instructivo 10/10

I was super skeptical about the windows key working but seeing that the owner was replying to people in subreddits made me pull the trigger, and it actually worked. What a great value, I will absolutely be recommending this to any of my family that happens to need a windows key and I highly encourage the skeptic buyer to give it a chance.
