Windows 10: Brand new windows 11 product key not working on new PC

Recently built a PC and got to the step where I install windows 11. Nothing seems to be wrong with running the program and installing via DVD. For some reason the product key isn’t being accepted by the system. There is no error code and I cannot open the command prompt. I bought the copy from newegg, which I believe gets it directly from Microsoft. Can somebody help?

Brand New windows key won't work.

I recently bought a windows product key from amazon for my newly built pc. I installed windows, inputted the product key.

All seemed fine. A day later it is prompting me to input the product key and when I do it is saying the key has been used on another computer. Baring in mind I bought this brand new from amazon.

Any suggestions?

 

I built a new computer running windows 11 home. Can I transfer my product key from my old windows 10 Pro?

How can I transfer my license to my new PC? I have verified it's a retail copy but I can't activate the product key and the upgrading hardware step doesn't list my new PC.

Do I need Windows 11 Pro or should the 10 Pro key automatically upgrade me?

How do I do this?

 

Install windows on a brand new SSD with product key


Hi,
Currently I'm using windows 10 on a HDD on my desktop.
The desktop used to run windows 8, but I upgraded it. (so the product key is used)

Using Belarc Advisor, I got my Windows 8 product key.
I have a brand new SSD here so I want to upgrade to this SSD.

However, the HDD is bigger than the SSD and I can't shrink the HDD to be smaller than the SSD.
Hence, I'm looking for a way to download Windows 8 iso file and use that iso file to install Windows 8 on my new SSD.

Is it possible to download a Windows 8 iso file with a used Windows 8 product key.
If the answer is yes, how do I do it?
