Downgrade from Windows 10 Enterprise to Professional without the loss of any data. You will need a valid Windows 10 Professional product key for this process.

[Solution 1] Activate Windows 10 Professional


  1. Open the Settings app and click Update & Security.
  2. Open Activation and click Change product key.
  3. Enter your Windows 10 Professional product key and click Next.
  4. Restart the computer after the new product key is activated.

You can force a downgrade with the default product key (VK7JG-NPHTM-C97JM-9MPGT-3V66T) of Windows 10 Professional, however this will not activate Windows.
