How It Works

Search Process

The script uses a runspace pool with multiple threads to concurrently search for the specified user's login status on various PCs within your Active Directory domain. Each thread executes the following steps:

Scriptblocks and Runspace Pools

The script uses PowerShell's built-in support for runspaces and scriptblocks to execute multiple threads concurrently. This allows the script to efficiently search for the specified user's login status on multiple PCs simultaneously.

Key Code Snippets

$Scriptblock = {
    #Get explorer.exe processes without credentials parameter if the query is executed on the localhost
    $proc = gwmi win32_process -ErrorAction SilentlyContinue -computer $Computer -Filter "Name = 'explorer.exe'"

    #If $proc is empty return msg else search collection of processes for username
    if ([string]::IsNullOrEmpty($proc)) {
        $results.Items.add("$user not found on $Computer!")
    } else {
        $progress++
        ForEach ($p in $proc) {
            $temp = ($p.GetOwner()).User
            if ($temp -eq $User) {
                $Results.ForeColor = 'green'
                $results.items.add("$User found logged on $Computer")
                $f = 1
            }
        }
    }
}
