Windows Server 2016 RDP certificate configuration

On windows 2016 as well as previous version, there is no utility for RDP Certificate configuration. We can do this levereging WMI interface. The simplest way for accomplishing that is Powershell script. Configuration script can be found below.

$CN = "CN=localhost"
$RdpSetting = Get-WmiObject -class "Win32_TSGeneralSetting" -Namespace root\cimv2\terminalservices -Filter "TerminalName='RDP-tcp'"
$thumbprint = (Get-ChildItem -path cert:/LocalMachine/My | | ? Subject -eq $CN).Thumbprint
Set-WmiInstance -path $RdpSetting.__path -argument @{SSLCertificateSHA1Hash="$thumbprint"}

Presented method is universal, so can be used on client version Windows 10 as well on the server Windows 2016.
