Finding your Windows server product key can be difficult. The product key is embedded in the activation software, and it is not shown in the system information (Settings -> System -> About) like in older Windows operating systems. There is no need to use third-party software that you don’t know if you can trust. Below we list several ways to locate your Windows Server license key.

Have your checked the Product Box or your email?

If you received a physical product, have you checked the box? There is usually a product key label on a card inside of the product box.

If you purchased a digital copy, you likely have the product key in your email, hopefully you didn’t accidentally delete the email.

Check your Microsoft Account or try contacting Microsoft Support.

If you purchased Windows from the Microsoft Store, your key will be stored digitally in the Microsoft account that you purchased it under. Login to the Microsoft store using your credentials, navigate to the downloads section, then to the product key, and click on subscription. Under the subscription menu, the product key will be under the digital content section.

CLI via Command Prompt/Powershell

Command Prompt (CMD)

  1. Open CMD with admin rights
  2. Run the following command:
    wmic path softwarelicensingservice get OA3xOriginalProductKey
  3. If you see a key, you are good to go, if not you have a digitally activated key


  1. Open Powershell with admin rights
  2. Run the following command:
    (Get-WmiObject -query 'select * from SoftwareLicensingService').OA3xOriginalProductKey
  3. If you see a key, you are good to go, if not you have a digitally activated key

Check the Registry Editor

If you are familiar with using the Registry editor, you may have luck finding your product key, but be careful not to edit anything unless you know what you are doing.

  1. Click your start icon, and type “regedit”
  2. Open “Registry Editor”
  3. Navigate to the path:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform
  4. Double-click on the “BackupProductKeyDefault” to find your product key (if digitally activated, this may not be the actual key).


If you have been in IT any amount of time, you should know that things are always changing. These methods may work now, but may not work in the future. If you find additional methods, please comment below and we will add and credit you with your method as long as we can repeat the finding.

We did not recommend any software options since there are many out there, and those looking for this information, would have already found several options while looking for this same information.
