Get regkey value on a batch of computers remotely.

Here's a Powershell script I created to get value in the registry on a batch of computers remotely.  Very handy if you have many computers to check.  Will output 'Offline' if the computer is turned off.

$strMachineName = Get-Content computer_name.txt
foreach ($line in $strMachineName)
{
    try{
            $reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $line)
            $regkey = $reg.OpenSubkey("<registry path>")
            $serialkey = $regkey.GetValue("LicenseInformation")
            if ($serialkey -eq ""){
                  write-host $line
           }
     }
    catch{
                write-host $line ----- "Offline"
    }
}
