There's a way that came out yesterday afternoon to install a module to check if this vulnerability is affected a system. I have created this article:
https://www.experts-exchange.com/articles/31438/Intel-Bug-Spectre-and-MeltDown.html

$computers = Get-Content "computers.txt"
$sb={
    Install-Module SpeculationControl
    Get-SpeculationControlSettings
}
foreach($computer in $computers){
   $comp= Invoke-Command -ComputerName computer -ScriptBlock $sb
  add-content -path "C:\log.txt" -value "$computer,$comp" 
}

Open in new window

I've just posted PS code to do the complete check for the domain at https://www.experts-exchange.com/questions/29076942/Meltdown-patch-Checker-script-for-remote-PCs.html?anchorAnswerId=42426331#a42426331. This would also work with a text file with a few simple changes.

no... i really don't want at this point meltdown patch os installed or mot.

my environment has mix of windows 2003, 2008, 2008 R2, 2012 and 2012 R2. microsoft has released patch for only 2008 R2 and 2012 R2. for the rest , registry fix can be applied. so i need get installed os of all my servers. i preference the server names passe from text file because we have many desktop like windows 10 also connected to domain.

Miles script should work for you. It just asks AD for the details, and so machines do not need to be online, and no credentials issues can arise.
