PowerShell: Remove old Az modules

I recently ran a Get-Modules -ListAvaiable and I saw a lot of older versions:

Get-Module -ListAvailable Az*

I wanted to remove all versions except the most recent. Here is my script:

foreach ($module in (Get-Module -ListAvailable Az*).Name |Get-Unique) {
if ((Get-Module -ListAvailable $module).Count -gt 1) {
$Latest_Version = (Get-Module -ListAvailable $module | select Version | Sort-Object Version)[-1]
write-host "Latest $module version $Latest_Version"
Get-Module -ListAvailable $module | Where-Object {$_.Version -ne $Latest_Version.Version} | foreach {Uninstall-Module -Name $_.Name -RequiredVersion $_.Version -verbose}
}
else {
Write-Output "Only one version installed for $module"
}
}

Hope that helps someone.
