Please follow the steps below to check the status of your license key.
Please click Start menu, then type in CMD, right click and run as administrator.
Then on the command prompt window type in
slmgr -dli
This will show the kind of license that you have. It can be one of three types: Retail (FPP (Full Packaged Product)), OEM (Original Equipment Manufacturer), and Volume Licensing. The last type is usually for organisations that have multiple license keys and are not for resale. It is the type that is most often used for pirate copies of Windows.
If it doesn't work with that command, type in this command instead then press enter.
slmgr /dlv
and then please copy and paste the result in our conversation. Thanks!
