This script is tested on these platforms by the author. It is likely to work on other platforms as well. If you try it and find that it works on another platform, please add a note to the script discussion to let others know. The OEM Activation 3.0 (OA 3.0) system enables original equipment manufacturers (OEMs) to develop an internal inventory management system to manage the ordering and receiving of Windows product keys and the creation and reporting process for the Computer Build Report through Microsoft-hosted web services or Microsoft Digital Operations Services (MDOS).
Background
Starting at Windows 10 Creators Update (build 1703), Windows activation behavior has changed so that the unique OA3 Digital Product Key (DPK) is not always presented as the currently installed key in the device. Instead, the system behaves as follows:
Windows Oem Activation Tool 3.0 Activation
Windows 10 (including all versions starting at Windows 10 Creators Update) is deployed to a device by having the appropriate default product key. You can run
slmgr /dliorslmgr /dlvto show the partial default product key instead of the OA3 DPK as the current license in the firmware. The product ID that is displayed on the Settings > System > About page is not unique for the Windows 10 key that is being used.A device that is running any Windows 10 OEM client edition, such as Windows Home or Windows Professional, and is activated by using the OA3 DPK in the firmware is upgraded to a newer version of Windows (for example, build 1703 to build 1709). However, sometimes running
slmgr /dliorslmgr /dlvIgi 4 download for pc. does not show the OA3 DPK as the current license. Instead, these commands show the default product key.
The behavior that is described here is by design. The activation and user experience are not affected. However, OA validation in the factory may be affected as follows:
- The output of the
slmgr /dlvorslmgr /dlicommand is not necessarily the last five (5) digits of the injected DPK. Therefore, you can no longer rely upon these commands to return the expected results.
Recommendations for validating the product ID against the product key ID of OA3 DPK
Every OEM has a different manufacturing process that they have adopted through years of experience in manufacturing Windows. Specifically, to validate the DPK against the installed Windows 10 edition, we recommend that you not rely on the output of slmgr /dlv or slmgr/dli but, instead, use the latest OA3Tool as follows:
OA3TOOL /Validate
Runs a validation pass to make sure that the MSDM table exists, the MSDM table header includes all the required fields, and the MSDM table entries exist and comply with the correct formats.
OA3TOOL /CheckEdition
Does a cross-check between the injected DPK and the target Windows edition if they match.
Can Microsoft ensure that the system will always activate if I do the recommended steps
The Windows activation system is designed to use the product key that is injected into the firmware of the computer during manufacturing. It automatically activates the device when the device first comes online. This operation is used daily on thousands of devices. As an additional check, OEMs are encouraged to run the complete end-to-end validation process, including activation on a subset of the devices, to validate the user experience with their PCs. If you experience any issues, engage with us through the usual channels.
Why did Microsoft remove the ability to check the last five digits of the product by using slmgr
SLMGR is a legacy tool. Although we have not updated slmgr, and because of updates in successive system builds, the last five digits of the product key that are shown by slmgr /dlv or /dli do not match the product key that is injected into the system BIOS. This is by design. We have no intentions of validating SLMGR for every Windows 10 release or making any other changes. We are very open to feedback regarding the OA3 tool and what additional capabilities we can add to it to improve the manufacturing flow.

Windows Oem Activation Tool 3.0 Download
Newer PCs and laptops shipping with Windows 7, Windows 8, and Windows 10 no longer come with a Certificate of Authenticity attached to the back or bottom of the PC. Instead, PC manufacturers have worked with Microsoft to embed the product key directly into the BIOS or EFI.
If you need to retrieve the OEM-embedded product key from your PC, you can use the NeoSmart OEM product key utility to extract and show the product key progammed into your PC. Absolutely no user interaction is required, you just run the download and it immediately displays the detected product key. This product key can be used to reinstall Windows 10 and Windows 8 with a clean Windows setup CD to remove cruft and bloatware installed by the manufacturer, or to reinstall Windows after a crash or system failure.
