Hello,
Do you currently have access to the Windows/device you are about to change SSD?
If so, Can you please type cmd in the search on the taskbar and hit enter to launch command prompt, then run the following command:
slmgr /dlv
Then share a screenshot please. Thanks!

Thanks for the update. The license is an OEM COA NSLP.
Microsoft is not able to provide the product key for this type of license. How did you obtain it? If it came with a custom built computer, check the device for a sticker. That sticker should contain the key. If you purchased the license separately, think back to whether the box or packaging might still be around, since the key would have been included there.
This license type is intended for system builders who do not have the ability to embed an OEM key into the motherboard like large manufacturers such as Dell or HP. It behaves similarly to a retail license, but builders must attach the COA sticker to the device the license is assigned to. It is not designed to be sold directly to end users. Builders can get support from Microsoft for these licenses, but individual end users cannot, since support is meant to go through the builder.
I have purchase key online likely like market place (kijji). Product key was kind cheap so i brought it. So, i belive i cannot retive them right.
I wish you didn't buy it from third party. They are cheap for a reason, because they are not meant to be sold to end users. And when you buy an OEM key, you accept the licensing terms that you wouldn't get support from MIcrosoft support directly, because such licenses are meant for builders, and authentorized builders do get support. I am sorry, I am afraid you would need to get a new license in this case. If you need a license that comes with qualified Microsoft support, it has to be a retail license.
