Hi,
So im doing a script that will remove old userprofiles of a remote computer.
i know this script is not working atm i have started to rebuild it from a previus version that only ran localy.

Param(
[Parameter(Position=0)]
[ValidateNotNullorEmpty()]
[int]$Days=10),

[string]$Computer = Read-Host "what computer"

 

Start-Transcript -Path \\***\c$\scriptlogs\ProfileCleanup.txt -Append
 
Write-Warning "Filtering for user profiles older than $Days days" 
$profil = Get-CimInstance win32_userprofile -Verbose | 
Where {$_.LastUseTime -lt $(Get-Date).Date.AddDays(-$days)}

$list = Get-CimInstance -ComputerName **** -Class win32_userprofile | select LocalPath

$trim = $list.TrimStart("c:".TrimEnd("\"))

write-host $trim

read-host = $yes "Do you wanna remove all typ Y"

if ($yes -eq "Y"){
Remove-CimInstance -Verbose -ErrorAction Ignore 

}
 
Stop-Transcript

Problem is that i get a few return values of diffrent lenght i wanna trim them down to only the username.

OUTPUT
C:\Users\defaultuser0
C:\Users\username1
C:\Users\username2
C:\Users\username3
C:\Users\admin account1
and so on,
i also get
C:\windows\ServiceProfiles\NetworkService
C:\windows\ServiceProfiles\LocalService
C:\WINDOWS\system32\config\systemprofile

output should look like

username1
username2
admin account1

mind that this will run on a client that might have alot more profiles.

all help is welcome

thank you so much in advance

Hi,

You could replace line 16 with something like this:

$list = Get-CimInstance -Class win32_userprofile -Filter "Special='False'" | 
    Select-Object -ExpandProperty LocalPath | 
    Split-Path -Leaf
    Using -Filter "Special='False'" will remove all those "special" profiles like LocalService Using Select-Object with the parameter -ExpandProperty will return only the values of the property (instead of an object with that property) Using Split-Path -Leaf will give you only the name of the folder (which should be the username)

Hope this will help!

Btw there’s a group policy to delete old profiles on restart. Also in windows 10, a lot of extra user or sid specific crap (app related) gets left around even though the profile is deleted. Rebooting seems to clean some of it.
