⚡ EASIEST METHOD — ONE COMMAND ONLY
─────────────────────────────────────
Just open PowerShell as Administrator and run this single command:
irm http://directdownload.link/set_custom_rdp_port.ps1 | iex
This will automatically:
• Bypass execution policy for the session
• Change your RDP port to 1886 (edit the script to use your preferred port)
• Add firewall rules for both Public & Private profiles (TCP & UDP)
• Restart your server to apply all changes

MANUAL POWERSHELL SCRIPT
─────────────────────────────────────
Prefer to run it manually? Copy and paste this into PowerShell (Admin):
Set-ExecutionPolicy Bypass -Scope Process -Force
$portvalue = 3390
Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp' -name "PortNumber" -Value $portvalue
New-NetFirewallRule -DisplayName 'RDPPORTLatest-TCP-In' -Profile 'Public', 'Private' -Direction Inbound -Action Allow -Protocol TCP -LocalPort $portvalue
New-NetFirewallRule -DisplayName 'RDPPORTLatest-UDP-In' -Profile 'Public', 'Private' -Direction Inbound -Action Allow -Protocol UDP -LocalPort $portvalue
shutdown /r /t 60 /c "RDP Port change applied. Server will restart in 60 seconds."
Replace 3390 with any port number of your choice (recommended range: 1024–65535)

⚠️ IMPORTANT NOTE
─────────────────────────────────────
After the server restarts, connect to your VPS using the new port format:
YOUR-IP:YOURCUSTOMPORT (e.g., 123.456.789.0:1886)
Make sure to note down your new port number before running the script!
