Need Help deleting all local user account through powershell

Hello,

I am trying to delete all local user accounts on machine through Get-wmiobject but getting error as below.

First: I retrieve all users with account type code -- 512 means local account and stored in avariable.

Second: After this I put say $a | remove-wmiobject.

Error:  This provider is not capable of doing this operation.

  • That is because this cmdlet is not for user objects. You can see this by looking at the properties an parameters available from the cmdlet.

    Remember, PoSH is looking for by property or by value when it takes a action on X or Y.

    What version of PoSH are you on. The latest version of PoSH have specific set of cmdlets for local user management.

    Microsoft.​Power​Shell.​Local​Accounts
    This section contains the help topics for the Local Accounts cmdlets in Windows PowerShell.
    'docs.microsoft.com/en-us/powershell/module/microsoft.powershell.localaccounts/?view=powershell-5.1'

    Otherwise, you have to use the ADSI / WinNT provider and do this manually,

    ADSI WinNT Provider
    The Microsoft ADSI provider implements a set of ADSI objects to support various ADSI interfaces. The namespace name for the Windows provider is "WinNT" and this provider is commonly referred to as the WinNT provider. To access the WinNT provider, bind to any of the ADSI objects of WinNT, using the WinNT AdsPath.
    'msdn.microsoft.com/en-us/library/aa772237(v=vs.85).aspx'

    User Creation with the ADSI LDAP Provider
    With the ADSI LDAP provider, you can only create a global user account. Local accounts reside in the SAM database and must be created using the WinNT provider. For more information about creating a user object with the WinNT provider, see WinNT User Object.
    'msdn.microsoft.com/en-us/library/aa746509(v=vs.85).aspx'

    or take advantage of pre-written / tweak-able stuff.
