How to Remove Windows 10 Product Key from BIOS Firmware of a Laptop

If you have a laptop that came with Windows 10 pre-installed, you may have noticed that the product key is embedded in the BIOS firmware of the laptop. This means that whenever you reinstall Windows 10, it will automatically detect and activate the product key from the BIOS, without asking you to enter it manually. This can be convenient, but it can also cause some problems if you want to transfer the product key to another laptop, or if you want to install a different edition of Windows 10.

In this article, we will show you how to remove the Windows 10 product key from the BIOS firmware of a laptop, so that you can have more control over your Windows activation and installation. Please note that this process is not recommended by Microsoft, and it may void your warranty or damage your laptop. Proceed at your own risk.

Step 1: Uninstall the Product Key from Windows

The first step is to uninstall the product key from Windows, so that it is no longer associated with your laptop. To do this, you need to open an elevated command prompt by right-clicking on the Start button and selecting \"Command Prompt (Admin)\". Then, type the following command and press Enter:

slmgr /upk

This command will uninstall the product key and display a confirmation message. You can also use the following command to clear the product key from the registry:

slmgr /cpky

After running these commands, your Windows 10 will become deactivated and show a watermark on the bottom-right corner of the screen.

Step 2: Remove the Product Key from BIOS

The next step is to remove the product key from the BIOS firmware of your laptop. This is more difficult and risky than uninstalling it from Windows, as there is no official way to do it. You will need to use a third-party tool called RWEverything, which can read and write data to any hardware device on your laptop. You can download RWEverything from here.

After downloading and installing RWEverything, run it as administrator and click on the ACPI icon on the toolbar. This will open a window with several tabs showing different ACPI tables. You need to find the tab that contains the MSDM table, which stores the Windows product key. You can use the Find function (Ctrl+F) to search for \"MSDM\" in each tab.

Once you find the MSDM table, you will see a hexadecimal code that represents your product key. You can copy this code by selecting it and pressing Ctrl+C. You can also use this online tool here to convert it to a readable format.

To remove the product key from the BIOS, you need to overwrite it with zeros or random characters. To do this, select the hexadecimal code in RWEverything and press Ctrl+R. This will open a dialog box where you can enter a new value for the selected data. You can enter 32 zeros or any random characters of your choice. Then click OK and confirm that you want to write data to MSDM.

After writing data to MSDM, you need to save changes and exit RWEverything. Then restart your laptop and check if the product key has been removed from the BIOS. You can use this command in an elevated command prompt to verify:

powershell \"(Get-WmiObject -query 'select * from SoftwareLicensingService').OA3xOriginalProductKey\"

If this command returns nothing or an error message, then it means that you have successfully removed the product key from the BIOS.

Step 3: Install Windows 10 with Your Desired Product Key or Edition

The final step is to install Windows 10 with your desired product key or edition. You can use a bootable USB drive or DVD to perform a clean installation of Windows 10. During the installation process, you will be asked to 061ffe29dd
