Hello,
How did you obtain your license initially?
Did it come with the device preinstalled, or did you purchase it?
If you purchased it, did you purchase from Microsoft, or from third party?
Is it originally a Win7/8 key?
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!
