Windows 10 Pro for Workstations

You have purchased a retail upgrade to Workstations.  If your new device has Windows 10 Pro then you can transfer the Workstations upgrade to it.  You need to contact the Answer Desk again and insist on the agent escalating the issue to a second level tech or a supervisor.  MSFT has the record of the purchase transaction and it is also in your Microsoft Account.  That should be everything MSFT needs to know to get you set up again.

Beautiful! It was my idea a week ago. Answer Desk is not to be able to find his own ass wit the both hands!

Everything was not install disk / ISO / serial number is simple fraud. You know I love to reinstall Windows often. This make me pleasure. Fraud Company must to rethink own policy. In people eyes they are still Windows and Office company.

I tell you what I must to do. Sent a register letters to Gates, Nadella, and European Commission.

That would work.

200 EUR is lot of money.

I can't help you with that.  I am a volunteer user trying to answer questions in the forum.  You have to deal with Microsoft.  I have no idea what you have or haven't done but no one here can help you with a licensing issue.  Only MSFT can do that.

That is handy. For future reference, the URL to open the page in the Microsoft Store App is: ms-windows-store://windowsupgrade/

Did you think, that I never try it???

Look

• the fraud company want to sell me one more time!!!!

Your new device requires a license for some Edition of Windows 10 in order to use an upgrade license to Pro for Workstations that had been purchased for your previous device.  Your Microsoft Account at https://account.microsoft.com ought to show a record of the Edition upgrade that was purchased.

Possibly you need to first purchase the same Edition of Windows 10 that you upgraded from on the previous device, unless the new device is already licensed for that same Edition.  What to do depends on the original Windows 10 Edition that was on the previous device prior to Pro Workstation and what Edition the new device is already licensed for.

Have a license. Four!!! I can tell you: MICROSOFT IS A FRAUD COMPANY !!!!!
