well got my key and everything okay. nothing happened wrong

Tengo una portátil con Windows 11 home de fábrica puedo actualizar con esta clave a Pro?sin necesidad de volver a formatear?

I’m really recommending this page. I’ve received a fresh retail code and all went very smoothly. Now I can change in system all I want! Thank you so much!

I bought but did not receive the details how to use it
you should guide

I wonder this cheap key worked fine then why people buy costly from Microsoft.
