How to obtain a product key for an OEM license

Question

PCメーカーから購入したＰＣ（OEM）に、同ＰＣでVLライセンス版でマスタを作成し一般化（共にWindows10 IOT Enterprise）

展開してプロダクトキーとしてOEMライセンスキーを入れようとしたが、キーがない、自動でアクティベーションもされていない（と思われる）。

コマンドプロンプトから　wmic path SoftwareLicensingService get /value | findstr OA3x

パワーシェルから　(Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey

Windows Product Key ViewerやProduKey等のツールで見てもエラーで取得出来ず。

メーカーは埋め込みなので確認出来ないと回答。

確認する方法、確認出来ない理由はわかりますでしょうか。

Hello

It sounds like you’re dealing with a complex issue related to OEM licensing and activation for Windows 10 IoT Enterprise.

About OEM Activation:

OEM licenses are typically embedded in the device’s firmware (BIOS/UEFI) and are not easily extractable using standard tools or commands.

The OA 3.0 (OEM Activation 3.0) system is used by OEMs to embed the product key in the device’s firmware.

Why You Can’t Extract the Key:

The product key is embedded in the firmware to prevent unauthorized use and piracy.

Standard tools and commands like wmic or PowerShell might not be able to retrieve the key if it’s protected or not exposed by the firmware.

Steps to Obtain and Use the Key:

Contact the Manufacturer: Since the key is embedded, the manufacturer should be able to provide guidance or support. However, if they can’t confirm it, you might need to escalate the issue within their support system.

Check Firmware Settings: Some devices have settings in the BIOS/UEFI that allow you to view or manage the embedded key.

Use Volume Licensing: If you have a Volume License (VL) version, you might consider using a Multiple Activation Key (MAK) or Key Management Service (KMS) for activation.

Creating a Master Image:

When creating a master image with a VL license, ensure that the image is generalized using sysprep to remove any specific hardware information.

Apply the appropriate VL key during the deployment process to ensure activation.

Further Resources:

Refer to Microsoft’s official documentation on Windows IoT Enterprise OEM Activation for detailed steps and guidelines.
