Multiple Remote Computers

We need to create a file for storing all the servers or multiple machines list, I named itas Allservers.txt for and saved it in my local machine c:\temp\Allservers.txt

$Allserers = get-content -path "C:\temp\Allservers.txt"
foreach ($oneserver in $allservers)
{
Write-host "currenty the Script is Running on"$oneserver
Get-WmiObject -ComputerName $oneserver win32_operatingsystem | % caption 
}

Find Windows Version Using Registry

Sometimes the result using WMI is a bit slow, we can also get the Windows version using registry, here is the simple Powershell code.

$Version = Get-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\'
$Version
$Version.ProductName
$Version.CurrentMajorVersionNumber
