How to Find Windows 10 Product Key in Registry (Simple Steps)

Windows 10 license key is stored in a special registry value. Here’s how you can find Windows 10 product key in the registry.

Windows 10 stores the registered product key in several different places including the Registry. To be more specific, Windows 10 stores the product in the DigitalProductId registry value. This is applicable to both Windows 10 Home and Windows 10 Pro editions. If you are scouring through the registry to find the product key, follow the steps shown below to make things easier. You will have the product key in no time.

Steps to Find Windows 10 Product Key in Registry

To locate the product key in the registry, these the steps you should follow.

  1. Right-click on the Start menu.
  2. Select the “Search” option.
  3. Search for “Registry Editor” and open it.
  4. In the registry, copy and paste the below path in the address bar and press “Enter“.
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
  5. On the right panel, find the “DigitalProductId” value.

That is it. DigitalProductId value stores your Windows 10 product key. Double-click on the value and you will see the encoded license key.

Decode or Decrypt DigitalProductId HEX Value to License Key

DigitalProductId is a binary value. Anything in a binary value is automatically converted into a HEX value. Since we want the product key and not a HEX value, we need to decode the DigitalProductID value. To do that we are going to use a free and open-source portable tool called WinProdKeyFinder.

To decrypt DigitalProductId value, follow the steps shown below.

  1. First, open the Registry Editor.
  2. Go to the following folder.
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\
  3. Right-click “CurrentVersion” folder and select “Export“.

  6. On the desktop, right-click on the .reg file and select “edit“.

Remove Windows 10 Product Key in Registry

These the steps you should follow to clear or remove Windows 10 product key in the registry.

  1. Open the Start menu in Windows 10.
  2. Search for “Command Prompt“.
  3. Right-click on the result and select “Run as administrator“.
  4. In the Command Prompt window, type “slmgr –cpky” and press Enter.
  5. The product key will be removed and you will see a “Product key from Registry cleared successfully” message.

That is it. It is that simple to remove Windows 10 product key in the registry.

Important note: Don’t delete the DigitalProductId value to remove the product key in the registry. You should always use command show in the above steps.

Digital License vs OEM or Retail Product Key

If you have upgraded from Windows 7 or Windows 8 to Windows 10 and linked your system to a Microsoft account then it is highly likely that you are using a Digital License.

You can check that by opening the Settings app. Open the Settings app and go to the “Update & Security → Activation” page. If it says “Windows is activated with a digital license linked to your Microsoft account” on the right pane then the system is using a digital license key.

In those cases, your system will be registered with a Windows 10 generic product key. As such, the Windows 10 product key you get from the registry is a generic key. A generic license key is only useful for temporary activation and not an alternative for the actual OEM or Retail Windows 10 product key.

That is all. I hope that helps. If you are stuck or need some help, comment below and I will try to help as much as possible.

      Even better! Thank you! No need for the download and copy/paste. Your forward slashes did not work for me, so had to go here to access:
      Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform

    I have bought a software in 2013 (kennel boarding system around 600€…), but the firm is down, mean no more after sale support.
    This software was activated both with an ID number and a password to activate online on the developper’s website.
    I have to install it on a new computer unfortunatly, I can’t find the mail with password, and no more access online registar. I try to clone the hard drive, but it doesn’t works, it is like I have to activate again the software. Is there a a way to fix my problem ? OR do I have to buy ( :-(( ) another software ?
    Thank you.
