[MS Windows] - How to extend trial version

Issue

Working within a LAB and/or in a nested environment often requires the deployment a Windows Server Machines (for instance, for a local services such as Active Directory, DNS, NTP and so on).
It may happen that the tests have not been completed, but the Windows trial period has expired.
Below I'm reporting few steps to extend the Windows Trial Period for other 180 days.

Solution

It is possible to "rearm" MS Windows (in my case Server 2022), extending the Trial Period of 180 days for 6 times each time. Let's see how to do that ...

Taking a look at the desktop, we can see the countdown in the corner down right. In my case, the period is expired.

Let's "run as administrator" a powershell, and run ....

slmgr -dlv

.. as we can see above, we still have 6 shots (Remaining Windows rearm count).

.. then, we rearm Windows .. running the command below and verifying that the command complete successfully ..

slmgr -rearm

.. we must restart the server, performing in powershell "Restart-Computer" or ..

shutdown /f /t 0 /r

When the Server will be newly up and running let's check that everything worked fine, performing the following commands...

slmgr -dli

slmgr -ato

slmgr -dlv

That's it.
