Use WMI to get current Windows username in VBA

Question

I was wondering if there was a simple way to use WMI to get you the current windows user name with domain. The Windows API call just gets you the short username, so you end up doing another call for the domain name. I have some code, but I get an automation error. Any ideas? I think I'm on the right path, but I am a little new to WMI.

Function GetFullName() As String
    Dim computer As String
    computer = "."
    Dim objWMIService, colProcessList As Object
    Set objWMIService = GetObject("winmgmts:\\" & computer & "\root\cimv2")
    Set colProcessList = objWMIService.ExecQuery _
        ("SELECT TOP 1 * FROM Win32_Process WHERE Name = 'EXCEL.EXE'")
    Dim uname, udomain As String
    Dim objProcess As Object
    For Each objProcess In colProcessList
        objProcess.GetOwner uname, udomain
    Next
    GetFullName = UCase(udomain) & "\" & UCase(uname)
End Function

UPDATE: see comments on accepted answer

Solution

There is no TOP 1 clause in WQL. Leave it out and your query should work:

"SELECT * FROM Win32_Process WHERE Name = 'EXCEL.EXE'"

What if someone else is logged into the box on another account? Does this strategy fall apart? Could it pick up the Excel that the other user might be running and return the incorrect info? btw, removing the TOP 1 worked.
