Our Windows templates are evaluation editions therefore it's not possible to simply enter a license key in the normal way.

Type the following command in command prompt (launched as administrator) to activate, replacing the X's with your license key:

Windows Server 2012/2016/2019 Standard:

DISM /online /Set-Edition:ServerStandard /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEula

Windows Server 2012/2016/2019 Datacenter:

DISM /online /Set-Edition:ServerDatacenter /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEula

Follow the instructions to restart the VPS after entering the above commands.
