Get User SID From Logon ID (Windows XP and Up)

Question

I have a Windows service that needs to access registry hives under HKEY_USERS when users log on, either locally or via Terminal Server. I\'m using a WMI query on win32_logon

Answer 1

Powershell is easier.

Function GetSIDfromAcctName()
{
$myacct = Get-WmiObject Win32_UserAccount -filter "Name = '$env:USERNAME " 
write-host Name: $myacct.name
Write-Host SID : $myacct.sid
}
