I've got the Win10 Pro key immediately, great service. Would recommend everyone.

todo me ha ido bien la clave a la primera

Bought to upgrade from Windows 11 Home to Pro but was getting errors saying I couldn't use the key to upgrade. Had to play around and got Windows 11 to go though the quick process of applying the Pro update by disconnecting from the internet - The small pop-up box reached 100%. After a reboot I got the Adding Features message but then it showed as Windows 11 Enterprise and clicking a link to the Windows Store said something like 'oops, sorry, we don't know how you got here but you can't buy this version of Windows' lol. Anyway, entered the key again and it has changed to a digitally licensed version of Windows 11 Pro.

Cheers :)

Works in Windows 11! For anyone wondering, this will work in Windows 11.

worked in like, 3 seconds, great key, and so inexpensive!!!
