Recover Windows 11 or 10 Product Key From BIOS/UEFI using Windows 10 Product Key Tool

Since the release of the Windows 7 operating system, product license keys have been embedded into the BIOS/UEFI by PC manufacturers as a standard practice. As a result, new Windows computers come preloaded with Windows 8, 8.1, 10, or 11 without displaying product key information or Certificate of Authenticity (COA) stickers on the device. This is because the product keys are embedded into the BIOS or UEFI, which can be accessed by entering the computer’s BIOS/UEFI.

While most Windows users never need to retrieve their product keys, as the pre-installed Windows image will automatically retrieve the product key during installation, problems arise when users need to reinstall Windows 7 / 8 / 8.1 / 10 on their device without a genuine product key. Without a product key, users cannot activate their Windows. However, third-party tools are available to retrieve the product key from the BIOS or UEFI, enabling users to avoid paying for a new product key from Microsoft after purchasing a pre-installed Windows 8 / 8.1 / 10 / 11.

Windows 10 Product Key Tool

The renowned BCD software team has developed a freeware application called the Windows 10 Product Key Tool. It is an efficient tool that allows users to easily retrieve product license keys for Windows 7, 8, 8.1, 10, and 11 from the BIOS or EFI. Once the product key is recovered, users can smoothly reinstall Windows and activate it.

To recover the product key from the BIOS or EFI of Windows 7, 8, 10, or 11, you need to run the OEM Product Key Tool on your computer. This software will automatically scan your BIOS or EFI and retrieve your Windows product key. You can then copy the retrieved key and use it for the reinstallation of Windows.

The Windows 10 Product Key Tool is compatible with both 32-bit and 64-bit versions of Windows 7, 8.1, 10, and 11.

If you receive an error message saying “Unable to open MSDM table!” instead of the product key, it indicates that the product key is not stored in your PC’s BIOS/EFI. In this case, you need to locate the product key sticker on your PC and make a note of it for future use.
