PowerShell custom Modify remote desktop RDP port

At the request of a friend, I wrote a script to modify the Remote Desktop through PowerShell. This script is not complicated. There are two options after the script is started: 1. custom Remote Desktop; 2. reply to the default port 3389 of Remote Desktop

The built-in cmdlets for Windows 8 and Windows 2012 are New-NetFirewallRule and Remove-NetFirewallRule.Therefore, this script is only applicable to Windows 8 and Windows and later versions., Pay attention to the applicable scope. If you want to be compatible with other versions of windows, replace the corresponding cmdlet with the netsh command. For how to use it, see the following help documentation http://technet.microsoft.com/library/hh831755.aspx

When modifying the RDP port, first modify the Registry "HKLM: \ SYSTEM \ CurrentControlSet \ Control \ Terminal Server \ WinStations \ RDP-Tcp the key value of "PortNumber" is the specified port, and then restart the Remote Desktop Services Service, add the firewall inbound request corresponding to the port to the firewall exception.

When restoring the default RDP port, first clear the previously added firewall exceptions, change the port with the corresponding key value in the Registry to 3389, and then restart the Remote Desktop Services Service.

It should be emphasized that during the restart of the Remote Desktop service, the Remote Desktop will be interrupted for a short time. You need to reconnect and add the firewall inbound requests corresponding to the port to the firewall exception, only the firewall at the operating system level is added here. If you are using a virtualization solution similar to Windows Azure, you must add an External Firewall exception, otherwise, the modified RDP port cannot be connected from outside.

Not much nonsense. Go to the Code:

Clear
Write-Host
Write-Host 1, custom Remote Desktop port-ForegroundColor 10
Write-Host 2. Restore the system's default Remote Desktop port-ForegroundColor 11
Write-Host
Write-Host
Write-Host "select an option from the above list... [1-2]"
$ Opt = Read-Host
Switch ($ opt)
{
1 {
Write-Host

Write-Host
Write-Host will prompt you to enter the port number to be specified. Please refer to the port range to enter a specified port number range: 1024 ~ 65535)
Write-Host: Modify the key value of PortNumber in the Registry "HKLM: \ SYSTEM \ CurrentControlSet \ Control \ Terminal Server \ WinStations \ RDP-Tcp.
Write-Host
# Enter the specified port number and modify the RDP default port
$ PortNumber = Read-Host "enter the port number range to be specified: 1024 ~ 65535 )"
$ Original = Get-ItemProperty-Path 'hklm: \ SYSTEM \ CurrentControlSet \ Control \ Terminal Server \ WinStations \ RDP-Tcp '-name' portnumber'
Write-Host the current RDP default port is $ original. PortNumber
$ Result = Set-ItemProperty-Path 'hklm: \ SYSTEM \ CurrentControlSet \ Control \ Terminal Server \ WinStations \ RDP-Tcp '-Name 'portnumber'-Value $ portnumber
If ($ result. PrimaryStatus-eq 'OK ')
{
Write-Host has completed RDP port modification! -ForegroundColor Green
}
Else
{

}
# Restart the remote desktop service

Write-Host: Add a firewall policy to allow the existing RDP port $ PortNumber to enter the site.
$ Result = New-NetFirewallRule-DisplayName "Allow Custom RDP PortNumber"-Direction Inbound-Protocol TCP-LocalPort $ PortNumber-Action Allow
If ($ result. PrimaryStatus-eq 'OK ')
{

}
Else
{

}
Write-Host

}
2 {

}

The following figure shows how to modify the RDP port:
