Where do I find Windows 10 Pro product key?
Smanthanp The Windows 10 product key can often be found in the Windows Registry, although it is stored in an encoded format. You can access the Registry Editor to view it, but the product key may not be readable in plain text without some additional steps. Here's how to find Windows 10 product key in the Registry.
Step 1: Press Win + R to open the Run dialog. Type regedit and press Enter. If prompted by User Account Control (UAC), click Yes.
Step 2: Browse to the following path (you can copy and paste it in the Registry Editor's address bar):
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersionStep 3: Look for the entry called DigitalProductId. The product key isn't directly displayed as a string. Instead, it's stored in a binary format.
Since the product key is not in plain text, you will need to use a script or software to decode it.
Matopias Below is a simple method using a PowerShell script to decode the Windows 10 Pro product key.
Press Win + X and select Windows PowerShell (Admin) or Windows Terminal (Admin). Run the Following Command:
(Get-WmiObject -query 'select * from SoftwareLicensingService').OA3xOriginalProductKeyPress Enter. If a product key is available, it will be displayed in plain text. This is a free way to help you find Windows 10 product key via regedit.
This works! Now to see if the Win10 key will work on a clean install of Win11. I did not want to do the upgrade so installed a new drive and clean install of 11.
