Find service pack levels for Windows using powershell

Compile a list of servers, may be using another powershell script querying your AD container for servers.







The script below also does a ping test. To be honest, ping test doesn't really tell me if wmi query is going to work.

#$erroractionpreference = "SilentlyContinue"
$serverlist = Get-content 'C:\temp\Serverslist.txt.txt'

Foreach ($server in $serverlist)
{
    if((test-connection -computername $server -count 1 -ea 0 -quiet) -eq $true)

    {
    $serveros = Get-wmiobject -class win32_operatingsystem -computername $server
        foreach ($objserver in $serveros)
    {
        $server + "; " +$objserver.caption + "; " + $objserver.ServicePackMajorVersion
    }
   
    }
}
