Hello Triyambak,
You could try this , hope WinRM and PS remoting are all good on those 1000+ servers
Function Get-IEVersion
Param([string]$computer = $env:COMPUTERNAME)
Write-Output $computer
Get-ItemProperty -path 'HKLM:\SOFTWARE\Microsoft\Internet Explorer' -ErrorAction SilentlyContinue | select-object Version,svcUpdateVersion | Select-Object -Property "Version",@{Name="Updated to Version";Expression="svcUpdateVersion"}
Then,
Get-Content C:\hosts.txt | foreach {Get-IEVersion -computer $_}
Where hosts.txt has the server details..
OR
get-content c:\hosts | foreach {[system.diagnostics.fileversioninfo]::GetVersionInfo("\\$_\C`$\program files\internet explorer\iexplore.exe") }
Regards,
V.
