This guide shows you how to remove your Windows 11 product key from your computer.

Why do this?

You might want to move your Windows license to a new computer. Or, you might be selling your current PC and want to keep your license for yourself. Removing the key ensures the new user does not have access to your specific activation rights.

What happens when done?

Once you finish, your computer will no longer be “activated.” Windows will act as if it is not licensed. You can then use that same product key on a different machine.

Note: This process does not delete your digital license from Microsoft’s servers. It only removes the key from the current device. If you run into issues moving the key later, you might need to call Microsoft support.

Important: You must have administrator privileges to perform these steps. %%LNK0%%

  1. Click the Start button.

Now, you will use a simple command to uninstall the key from your system.

💻Code
slmgr /upk

Press Enter on your keyboard. This command tells Windows to stop using the current product key.

Next, you need to clear the key from the Windows registry so it is completely removed from the system files.

💻Code
slmgr /cpky

Press Enter again. You should see a confirmation message stating that the product key has been cleared from the registry.

Summary

Removing your Windows 11 product key is a quick process that involves two simple commands in the Command Prompt. This is a helpful step if you are moving to a new computer or preparing your current PC for sale. Remember that this does not cancel your license, but it does leave your current computer in an unactivated state until a new key is entered.
