You may try below one, should work for filtering only "Windows Xp" guest VMs.
--------------------------------------------------------------------------------------------------------------------------
$vms = Get-VM
Foreach ($vm in $vms){
if ((Get-View $vm).Guest.GuestFullName -match "windows xp"){
Write-Host $vm.Name, " => " , (Get-View $vm).Guest.GuestFullName
}
}
--------------------------------------------------------------------------------------------------------------------------
You can check keeping "Xp" instead of "Windows Xp", it should also work..
