Cleanup-UserProfiles quickly delete unused profiles from the local machine

hello
I ran the script from admin Powershell ISE , but nothing happened.
what am I do wrong?

I'm trying to run the script but receiving the following error, please advise:

Exception calling "ParseExact" with "3" argument(s): "String was not recognized as a valid DateTime."

Steve, the error is coming from user accounts with no LastUseTime value, you can use the following to see which accounts are causing issues, most likely default accounts that exist but have not logged in:

Get-WmiObject -Class Win32_UserProfile | Where{$_.LastUseTime -eq $Null} | Select LocalPath, LastUseTime | Sort-Object LocalPath

This issue doesn't appear to cause problems as the "$DateLastused -ge $DateLimit" check fails but it can cause concern seeing a load of red flying by.

Possible way to get around this, if the LastUseTime is Null then set the $DateLastUsed value to be today's date/time so there is always a valid value and the profile won't be deleted.

So wrap this code in an If/Else:
    #Check if profile is in date range
    $dateLastUsed = [datetime]::ParseExact(($profile.lastusetime -replace '\..+$',''),'yyyyMMddHHmmss',$null )

Hey Shane... How to increase the duration from 60 days to 365 days

Nevermind... I got the option in the script... Thanks
