You will have the product key in no time.

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.
- First, open the Registry Editor.
- Go to the following folder.
- Right-click "CurrentVersion" folder and select "Export".
- Name the file anything you want and save it on the desktop.
- Close the registry editor.
- On the desktop, right-click on the .reg file and select "edit".
- In the file, find the "DigitalProductId" value.
- Copy the full HEX code along with its value name as shown in the image below.
- Next, download WinProdKeyFinder from Github.
- Open the ZIP file and extract the EXE file to your desktop.
- Double-click on the "WinProdKeyFind.exe" to open it.
- In the app, click on the "Decode DigitalProductID" button.
- Press Ctrl + V keyboard shortcut to paste the copied HEX code.
- Click on the "Parse DigitalProductId" button.
- As soon as you press the button, the application will decode the HEX code and shows the Windows 10 product key.
To copy the product key, click on the "Copy key to clipboard" button. You can paste the copied key in a text file or other document for safekeeping.

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.
