Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

When you look at HKEY_USERS registry key, each subkey (representing each user's settings) looks something like S-1-5-18 which is called SID I guess.

How do I know which SID is for which user account?

One can use PsGetSid also.

I use the following VB Script, rather than installing additional utilities. I can't take credit for the individual components of it, just the combination of them:


strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")

UserName = UserInput( "Enter the user name:", "" )
Domain = UserInput( "Enter the domain / PC name:", "")

Set objAccount = objWMIService.Get _
("Win32_UserAccount.Name='" & UserName & "',Domain='" & Domain & "'")
Call UserInput( "The SID for " & Domain & "\" & UserName & " is: ", objAccount.SID )

Function UserInput( myPrompt, default_text )
' This function prompts the user for some input.
' When the script runs in CSCRIPT.EXE, StdIn is used,
' otherwise the VBScript InputBox( ) function is used.
' myPrompt is the the text used to prompt the user for input.
' The function returns the input typed either on StdIn or in InputBox( ).

    ' Check if the script runs in CSCRIPT.EXE
    If UCase( Right( WScript.FullName, 12 ) ) = "\CSCRIPT.EXE" Then
        ' If so, use StdIn and StdOut
        WScript.StdOut.Write myPrompt & " "
        UserInput = WScript.StdIn.ReadLine
        ' If not, use InputBox( )
        UserInput = InputBox( myPrompt,, default_text )
    End If
End Function

Look at the keys in the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
