    How to Clear Product Key from Registry in Windows

    information   Information
    When you install and activate a retail copy of Windows, the product key is stored in the registry. This can be helpful to be able to use a program like ShowKeyPlus to view your installed product key if lost.

    However, having your installed product key in the registry could leave it vulnerable to being stolen from disclosure attacks by malicious software. Clearing the product key from the registry will prevent this, but you will need to make sure to keep a copy of your product key written down and kept in a secure location.

    This tutorial will show you how to permanently clear the product key from the registry to prevent it from being stolen in Vista, Windows 7, Windows 8, and Windows 10.

    You must be signed in as an administrator to be able to clear the product key from the registry.

    Note   Note
    This will not remove an OEM Windows 8/8.1/10 product key embedded in the UEFI firmware chip.

    If you run the slmgr /dli command in a command prompt, you will still be able to see the last 5 characters of the installed product key to help let you know what key you used to activate Windows with.

    Hmmm... Shawn, makes me wonder... whether I should include an encryption function on the keys in the registry, that can only be decrypted with ShowKeyPlus?

    64-bit Windows 10 Pro build 14393.3

    That would be a good idea to have that included.
