Hello Patiphon.C,
Thank you for posting in Microsoft Community forum.
To check the activation status and find the product key used on your server, you can use the following commands in the Command Prompt:
Check Activation Status
- Open Command Prompt as Administrator:
- Press Windows + X and select Command Prompt (Admin) or Windows PowerShell (Admin).
- Enter the Command:
- Type the following command and press Enter:
slmgr /xpr
- This command will display a window showing the activation status of your Windows Server.
Find the Installed Product Key
- Open Command Prompt as Administrator:
- Press Windows + X and select Command Prompt (Admin) or Windows PowerShell (Admin).
- Enter the Command:
- Type the following command and press Enter:
wmic path softwarelicensingservice get OA3xOriginalProductKey
- This command will display the original product key stored in your server's BIOS or UEFI firmware.
These commands should help you verify the activation status and identify the product key used on your server. If the product key is still valid and hasn't been activated on another device, you should be able to use it for your new server. If you need further assistance, feel free to ask!
I hope the information above is helpful.
If you have any question or concern, please feel free to let us know.
Best Regards,
Haijian Shan
