Run powershell script as Administrator at startup （Windows10)

• Run with Task Scheduler open highest privileges
• *.ps1 can't run directly, need extra command file *.cmd

Case

• My files locate in C:\Users\jiang\Documents
• My script is used to export WSL2 ports to LAN.

Create powershell script

wsl2-export-ports.ps1

$remoteport = bash.exe -c "ifconfig eth0 | grep 'inet '"
$found = $remoteport -match '\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}';
if( $found ){
  $remoteport = $matches[0];
} else{
  echo "The Script Exited, the ip address of WSL 2 cannot be found";
  exit;
}
#[Ports]
#All the ports you want to forward separated by coma
$ports=@(7101,8101,8301);

#[Static ip]
#You can change the addr to your ip config to listen to a specific address
$addr='0.0.0.0';
$ports_a = $ports -join ",";

#Remove Firewall Exception Rules
iex "Remove-NetFireWallRule -DisplayName 'WSL 2 Firewall Unlock' ";
#adding Exception Rules for inbound and outbound Rules
iex "New-NetFireWallRule -DisplayName 'WSL 2 Firewall Unlock' -Direction Outbound -LocalPort $ports_a -Action Allow -Protocol TCP";
iex "New-NetFireWallRule -DisplayName 'WSL 2 Firewall Unlock' -Direction Inbound -LocalPort $ports_a -Action Allow -Protocol TCP";
for( $i = 0; $i -lt $ports.length; $i++ ){
  $port = $ports[$i];
  iex "netsh interface portproxy delete v4tov4 listenport=$port listenaddress=$addr";
  iex "netsh interface portproxy add v4tov4 listenport=$port listenaddress=$addr connectport=$port connectaddress=$remoteport";
}
echo "Success!";

Create command file to running ps1

wsl2-export-ports.cmd

PowerShell -Command "Set-ExecutionPolicy Unrestricted" >> "C:\Users\jiang\Documents\wsl2-export-ports.txt" 2>&1
