Get-UserProfile

function Get-UserProfile{
        <#
        .SYNOPSIS
            Use WMI to query a computer about local profiles on the machine
        .Description
            This Fucntion is used to get information about local profiles on a computer. This will return information about any local profile, including the local cache of the domain accounts. By default returns the SID, Local path, and Last Use Time of the account; the -verbose flag can be used to return additional information.
        .PARAMETER UserID
            UserID to search for. If left blank will default to all users. By default UserID must match exactly, but you can use the wildcard '%' to perform more general seraches
        .PARAMETER Computer
            Computer to query for user accounts. Leaving Blank will default to 'localhost'.
        .PARAMETER ExcludeSystemAccounts
            Filters out System accounts (e.g. System, Network Service). This is done by looking at the 'special' property, which does not filter out users non-windows programs may create.
        .PARAMETER OnlyLoaded
            Setting this parameter shows only profiles that are currently in Use -- Combine with -ExcludeSystemAccounts and you can get a pretty good idea of who is currently logged into a machine.
        .PARAMETER ExcludeLoaded
            Returns only user profiles that are not currently in use. This is useful if you need to clear out profiles.
        .PARAMETER Verbose
            Returns Full user porfile data, rather than the default SID,LocalPath,LastUseTime
        .PARAMETER OlderThan
            Filter Results based on datetime. This requires a datetime object
        .Example
            Get-UserProfile -UserID MyUser
            Basic usage to see if the user "MyUser" exists on the local machine.
        .Example
            Get-UserProfile -Computer RDSServ1.mydomain.com
            Lists all user Profiles from remote computer "RDSServ1.mydomain.com"
        .Example
            Get-UserProfile -Computer RDSServ1.mydomain.com -ExcludeSystemAccounts -OnlyLoaded
            Lists non-system user profiles from remote computer currently marked as loaded. This gives a pretty good idea of who is currently logged into a remote machine.
        .Example
            Get-UserProfile -OlderThan $((get-date).adddays(-14))
            Lists user profiles that have not been used on the localhost in 14 days.
