Take care when deleting profiles, you don't want to hit machine special accounts. The Win32_UserProfile class has a LastUseTime property you can rely on.

$session = New-CimSession -ComputerName $cn$gcimParams = @{    'CimSession' = $session    'ClassName'  = 'Win32_UserProfile'    'Filter'     = 'RefCount<1 and Special="false" and Loaded="false"'}$profileList = (Get-CimInstance @gcimParams).Where{$PSItem.LastUseTime -lt (Get-Date).AddMonths(-6)}foreach ($user in $profileList){    $user | Remove-CimInstance -CimSession $session}
