Excelente. Compré una licencia de windows 10 iot y funcionó perfecto.

I'm skeptical of the reviews on sites like this but I figured I'd leave this for those who want to know. It worked without issues. No phone required. I'll try to remember to update this if it changes.

It actually activates my copy of Windows 10 LTSC 2021 IoT! Recommended.

I am very impressed by the support that is given here! After the initial purchase my key was working at installation but did not pass the activation.
After giving some information (including screenshots) I received a new working key but it was for the wrong version of Windows (Windows 10 Enterprise LTSC)
I contacted the support desk again and received a working key for the IoT version. All this within minutes of sending my emails. Really fast support and help when needed.
I will certainly purchase more keys from gamers-outlet.net in the future!

Activated without problem. W10 IOT LTSC is the best solution for hardware that isn't ready for scrap heap but won't meet W11 requirements and can't change to Linux because of app requirements.
