I have a retail copy of 10 pro which showed the last for digits in the activation page. I did a clean install of win upgrade(1607) and applied the licence number at install. On checking the activation page it was changed to "Digital Licence", not Digital Entitlement. So I entered my licence number just to see what would happen and the answer was "already Licensed.
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.
There is a huge public misconception on many sites that the digital licence is linked with the account, so if you login with an MS account, it activates. This is not the case.
All the link does is "remember" where your digital licence is on the current activation servers (maybe makes a copy on your MS account?), so if it FAILS to activate due a hardware changes (new mobo id does not match record), you can activate it manually as the link tells pc where to find your digital licence.
Thus removing device from the MSA account does not remove the digital licence, only the pointer to it on the activation servers (or maybe just a copy).
I have tested this - I logged in with MS account in VM with a digital licence, deleted device from VM. the reinstalled clean using a local login account (so device does not reappear on MS account), and it still activates ok.
Yes, just deleting the device doesn't remove the digital license. It would be one way (I think) to remove it from your account if you resold the PC with Windows 10 installed and activated with the digital entitlement. Its what I was thinking when I posted it. I could have worded it better. I've done countless clean installs and deleted the device, wash rinse and repeat. I usually change the name of the PC so I can tell at a glance which one is which in my devices list. Some times when I do that the new name shows up and the old one stays put too. I just delete the old one to clean things up.
As I understand these new licensing:
The term Digital Entitlement was changed to Digital Licensing
Using a MSA to sign-in associates the licensing information with your MSA. How it does that is unimportant, but the implications are important - clean installing Win10 after hardware changes will be activated using the Digital License tied to your Microsoft account.
If you install different editions on the same machine and sign-in with a MSA, there is a Digital License tied to your Microsoft account license for each edition.
I have not tested this, but there are statements re: MSA and Local accounts: Change the sign-in to a local account and the digital license is gone. It doesn't make sense to me, but I've seen it in a few places (sorry, no citation). It would make more sense if the machine was installed with a Local account (no way to associate anything on your MSA), but once the license is tied to your MSA ????
Always interesting to read your posts.
