I did not expect it for the 4 euro's to work but it did perfectly! It upgraded by windows 10 home version to pro and it didn't require any weird tools. Highly recommend.

I was not expecting the code to work for this amazing price but i took a chance and bought a key. To my surprise it worked and the code was available instantly and my windows was activated successfully! Will definitely recommend this to anyone!

Perfecto, se recibe al instante y funciona. Volveré a comprar
