Delete local windows profile with PowerShell

Question

I am trying to write a script that will delete the local profile of a test account. I am using the following line to return the SID of any account that starts with "test-"

PowerShell: $UserSID = (Get-WmiObject Win32_UserProfile | Where {$_.LocalPath -like '*\test-*'}).SID

Once I had the SID I used wmic to do the deletion but, I am not sure how to translate that code into PowerShell.

WMIC:wmic /node:"localhost" path win32_UserProfile where Sid="%%b" Delete

Answer 1

I was thinking this would work, but I don't find a delete method on the Win32_UserProfile class

$UserSID = (Get-WmiObject Win32_UserProfile | Where {$_.LocalPath -like '*\test-*'}).SID
(gwmi -class Win32_UserProfile -filter "SID='$UserSID'").Delete()

Answer 2

You can also just call the Delete method directly in a single statement:

(Get-WmiObject Win32_UserProfile | Where {$_.LocalPath -like '*\test-*'}).Delete()

Answer 3

Another reason of getting Exception calling "Delete" with "0" argument(s) is the user you're trying to delete is currently logged in. Log him off and try again.

Answer 4

I resolved this issue by opening Powershell as administrator (right click, Run as Administrator).

Answer 5

Get-WmiObject Win32_UserProfile -Filter "RoamingConfigured = 'True'" | Remove-WmiObject

True - Roaming profile
False - Local Profile
