+# Minecraft Windows Network Configuration
+
+This guide provides PowerShell commands to configure Windows Firewall for Minecraft networking.
+
+## Prerequisites
+
+- Windows 10 or later
+- PowerShell running as Administrator
+- Java Runtime Environment (JRE)
+
+## Check Installed Java Versions
+
+First, let's check which Java versions are installed on your system:
+
+```powershell
+# List all Java installations
+Get-Command java -ErrorAction SilentlyContinue | Select-Object Source
+Get-ChildItem "C:\Program Files\Java" -ErrorAction SilentlyContinue
+Get-ChildItem "C:\Program Files (x86)\Java" -ErrorAction SilentlyContinue
+Get-ChildItem "$env:LOCALAPPDATA\Programs\Java" -ErrorAction SilentlyContinue
+Get-ChildItem "$env:APPDATA\ATLauncher\jre" -ErrorAction SilentlyContinue
+```
+
+## Firewall Configuration
+
+Open PowerShell as Administrator and run the following commands:
+
+### 1. Allow Java through Windows Firewall (Dynamic Selection)
+
+```powershell
+# Function to create firewall rules for a specific Java path
+function Add-MinecraftJavaFirewallRules {
+    param (
+        [string]$JavaPath
+    )
+    
+    if (Test-Path $JavaPath) {
+        Write-Host "Adding firewall rules for Java at: $JavaPath"
+        New-NetFirewallRule -DisplayName "Minecraft Java" -Direction Inbound -Program $JavaPath -Action Allow
+        New-NetFirewallRule -DisplayName "Minecraft Java" -Direction Outbound -Program $JavaPath -Action Allow
+    } else {
+        Write-Host "Java path not found: $JavaPath"
+    }
+}
+
+# Get all possible Java paths
+$javaPaths = @(
+    "C:\Users\rob\AppData\Roaming\ATLauncher\jre\bin\java.exe",
+    "C:\Program Files\Java\*\bin\java.exe",
+    "C:\Program Files (x86)\Java\*\bin\java.exe",
+    "$env:LOCALAPPDATA\Programs\Java\*\bin\java.exe"
+)
+
+# Find all existing Java installations
+$foundJavaPaths = $javaPaths | ForEach-Object { Get-ChildItem $_ -ErrorAction SilentlyContinue } | Select-Object -ExpandProperty FullName
+
+if ($foundJavaPaths.Count -gt 1) {
+    Write-Host "Multiple Java installations found:"
+    for ($i = 0; $i -lt $foundJavaPaths.Count; $i++) {
+        Write-Host "[$i] $($foundJavaPaths[$i])"
+    }
+    
+    $selection = Read-Host "Enter the number of the Java installation to use (or 'all' for all installations)"
+    
+    if ($selection -eq 'all') {
+        foreach ($path in $foundJavaPaths) {
+            Add-MinecraftJavaFirewallRules -JavaPath $path
+        }
+    } else {
+        $index = [int]$selection
+        if ($index -ge 0 -and $index -lt $foundJavaPaths.Count) {
+            Add-MinecraftJavaFirewallRules -JavaPath $foundJavaPaths[$index]
+        } else {
+            Write-Host "Invalid selection"
+        }
+    }
+} else {
+    # If only one Java installation is found, use it automatically
+    if ($foundJavaPaths) {
+        Add-MinecraftJavaFirewallRules -JavaPath $foundJavaPaths[0]
+    } else {
+        Write-Host "No Java installations found"
+    }
+}
+```
+
+### 2. Open Required Minecraft Ports
+
+```powershell
+# Allow Minecraft default port (25565)
+New-NetFirewallRule -DisplayName "Minecraft TCP" -Direction Inbound -LocalPort 25565 -Protocol TCP -Action Allow
+New-NetFirewallRule -DisplayName "Minecraft UDP" -Direction Inbound -LocalPort 25565 -Protocol UDP -Action Allow
+```
+
+### 3. Verify Rules
+
+```powershell
+# List all Minecraft-related firewall rules
+Get-NetFirewallRule | Where-Object DisplayName -like "*Minecraft*" | Format-Table DisplayName, Enabled, Direction, Action
+```
+
+## Removing Rules
+
+If you need to remove the firewall rules, use these commands:
+
+```powershell
+# Remove Minecraft firewall rules
+Remove-NetFirewallRule -DisplayName "Minecraft Java"
+Remove-NetFirewallRule -DisplayName "Minecraft TCP"
+Remove-NetFirewallRule -DisplayName "Minecraft UDP"
+```
+
+## Notes
+
+- Make sure to run PowerShell as Administrator
+- The script will automatically detect Java installations
+- Default Minecraft port is 25565, adjust if using a different port
+- These rules allow both incoming and outgoing connections for Minecraft
+
+## Troubleshooting
+
+If you experience connection issues:
+
+1. Verify the rules are enabled:
+```powershell
+Get-NetFirewallRule -DisplayName "Minecraft*" | Select-Object DisplayName, Enabled
+```
+
+2. Check if the ports are actually open:
+```powershell
+Test-NetConnection -ComputerName localhost -Port 25565
+```
+
+3. Ensure Java is running with proper permissions:
+```powershell
+Get-Process java | Select-Object Id, ProcessName, Path
+```
+
+4. Check Java version:
+```powershell
+java -version
+```
