Frequently asked questions
How do we keep our prices so low?
Digital fulfillment and volume sourcing let NDWS Market price many products below typical retail levels.
Are our codes/keys real?
Yes. NDWS Market products are sold for legitimate activation and standard digital delivery.
How long does it take to get my order?
Most orders are delivered within minutes, although verification or payment checks can occasionally add some delay.
Do we ship by post?
Software keys and digital products are delivered electronically. Physical shipping only applies when a listing clearly includes hardware.
How can I download/view my code/key?
You receive the key and any included instructions by email after checkout, so you can access the product details digitally.
Are there subscription fees for your product keys?
No recurring subscription is added unless the product itself is specifically sold as a subscription-based license.
Can I redeem/activate my product key later?
Usually yes, but activating sooner is still the safer option so you can confirm everything is working while the order is fresh.
I do not know how to activate my product key.

Es una iso y no la he instalado
Solo se puede instalar ejecutando un archivo ISO, por lo tanto desconfío que sea realmente genuino, la clave no es reconocida por Microsoft, por lo que no lo he instalado y a la petición de la devolución del dinero, no la han realizado. Escudas. No lo recomiendo

Excelente, sem erros e funciona muito bem, recomendo.

Provided Key is Not working
MS Office could not be activated as the key obtained seemed to be already used. Several attempts at Royal key support to obtain new key which is working were not successful. Weak support in case of issues of Royal Key Team!
