MSSQL: Renewing Windows 2016 Server Standard Edition

Once the Windows Server 2016 trial is expired, it tends to just shut down. Activating will be impossible as it will no longer providing the option to enter the serial keys. The workaround is to re-arm the trial period

Bring up 'cmd' with Administrator mode.

slmgr -dlv

It will show the Remaining Windows rearm count. The user can rearm the trial license for a total of 6 times and 180 days for each.


Re-arm and restart the Windows.
slmgr -rearm

Now, activation should enable the user to enter the serial key by selecting "Change product key" if the user has a serial key instead of continuing to use trial periods.
