By using a new activation key on the KMS server, which also supports Windows Server 2022 and Windows 11, Windows Desktop LTSC versions (Windows 10 2015 LTSC, Windows 10 2016 LTSC, Windows 10 2019 LTSC, ...) cannot be activated at the moment. Windows Desktop (annual/semi-annual) Education and Enterprise versions are NOT affected by this.
TU.it is in close contact with Microsoft Support to solve the licensing issue as soon as possible.
Microsoft has recognized the error and is working on a fix. Unfortunately, a time estimate for the availability of a fix is not yet known.
For devices that meet the Windows 11 criteria, it is possible to upgrade from 2019 LTSC to Windows 11 Enterprise while retaining all programs and settings.
Since to date neither a solution nor a workaround for the problem could be presented by Microsoft, TU.it has decided to implement a workaround itself. This workaround is based on a 3rd temporary KMS, which is provided with the old key for the LTSC versions. By changing the activation script, the LTSC versions (until the solution from Microsoft) will be routed to the temporary KMS.
As soon as the workaround is implemented and tested, we will inform you accordingly.
To date, neither a solution nor a workaround has been found by Microsoft. Therefore, TU.it has now implemented the announced workaround and released it with immediate effect.
The activation problem can be solved by updating the activation script to at least version 184.108.40.206. The update can be done within the activation script by using the link on the bottom left or by using the TUtoolbox.
