Windows 10 Pro Digital License

The Windows 10 Pro Pack purchased is registered to your Microsoft Account. You will be able to retrieve the Windows 10 Pro license if you reinstall Windows 10 Home, by running the Activation Troubleshooter.

Activation switched from "with product key" to "with Digital License"

In the past, if I did a change product code on my 10 Pro install, and entered my Education key. Activation switched from activated with a digital license to activated with a product code. And it would list the last 5 digits of the code.
Now when I do that it stays as activated with a digital license. The DL is upwards compatible, as far as I know. I can clean install 1511 Pro or 1607 Pro on this PC with a skip key and they will both activate. I do believe its edition specific (Home, Pro, etc) but not build specific. I've installed an older insider build on a PC that never had an insider build on it and it activated just fine on the 10 Pro DL that PC had gotten with the free upgrade.

Right now, I only have the one PC that doesn't have a DL for the education version. I've delayed activating it in 1607 so I can do more tests. Once its activated in 1607 there is no going back.

 

Digital license

Thats how licensing works with Windows 10, the digital license is attached to your Microsoft Account and makes it easy to reactivate Windows 10 in the event you reinstall it.
