PowerShell script, Search multiple devices running a specific version of IE.

I was querying multiple devices running a legacy OS, to check if they are running Internet Explorer v 6, 7 or 8 on the desktop or adjacent desktop spaces. Used this PowerShell.

# Define an array of computer names
$computerNames = @("A_VM_00003", "A81218", "95715", "A95917", "A96288", "A98785", "CWS027", "NET270CLA", "CITAPP08", "QSTR01")

# Function to check IE version on a single computer
function Check-IEVersion($computerName) {
    Write-Output "Checking $computerName..."

    # Get all running Internet Explorer processes
    $ieProcesses = Get-WmiObject -Class Win32_Process -ComputerName $computerName -ErrorAction SilentlyContinue | 
        Where-Object { $_.Name -eq "iexplore.exe" }

    if ($ieProcesses) {
        foreach ($process in $ieProcesses) {
            # Get the IE version from the registry
            $ieVersion = Invoke-Command -ComputerName $computerName -ScriptBlock {
                $regKey = "HKLM:\SOFTWARE\Microsoft\Internet Explorer"
                (Get-ItemProperty -Path $regKey -Name "Version" -ErrorAction SilentlyContinue).Version
            } -ErrorAction SilentlyContinue

            # Check if the version is 6, 7, or 8
            if ($ieVersion -match "^[6-8]\.") {
                $processInfo = Get-WmiObject -Class Win32_Process -ComputerName $computerName |
                    Where-Object { $_.ProcessId -eq $process.ProcessId }
                
                $windowTitle = $processInfo.GetOwner().User

                Write-Output "  Internet Explorer $ieVersion is running on $computerName"
                Write-Output "  Process ID: $($process.ProcessId)"
                Write-Output "  Window Title: $windowTitle"
                Write-Output "  -----------------------------"
            }
        }
    } else {
        Write-Output "  No Internet Explorer processes found running on $computerName"
    }
    Write-Output ""
}

# Main script execution
foreach ($computer in $computerNames) {
    Check-IEVersion $computer
}
