Useful scripts

List all servers (better FQDN or IP) in a txt file name "servers.txt". Keep the PowerShell script (say script.ps1) at the same location as the text file. $server=Get-Content C:\servers.txtInvoke-Command -ComputerName $server -FilePath C:\script.ps1

Create a text file (.txt) with the name "serverlist.txt" and mention all server's FQDN. In this example, we will get the hotfix details from 1st August to 30th August 2022. Note: The date in this script will be MM/DD/YYYY $server = Get-Content .\serverlist.txtGet-Hotfix -ComputerName $server | Where { $_.InstalledOn -gt "8/1/2022" -AND $_.InstalledOn -lt "8/30/2022" } | Select-Object pscomputername,description,hotfixid,installedby,installedon | Export-Csv August_Patch.csv
