I use this small script to occasionally update my most used modules so I can copy them to systems I manage or to a network share.

Save-CommonModules.ps1

# These are moudles that I need to routinely save from the PowerShell Gallery
$modules = @("Pester","dbatools","dbachecks","psTrustedHosts","PoshWSUS","PSWindowsUpdate","PSDecode","PoshRSJob","PSFramework",
    "ScheduledJobTools","WindowsCompatibility","ImportExcel","BurntToast","Invoke-CommandAs","PoshEvents","psbbix","UniversalDashboard.Community")

$path = Read-Host -Prompt 'Please enter the full path to which you want to save common modules:'

Foreach ($module in $modules) {

    Save-Module -Name $module -Path $path -AcceptLicense -Force
    
}
