I don't believe there is a standard set across all windows OS, but you can
see yours with

Sub ListEnviron()
On Error Resume Next
rw = 1
For i = 1 To 100
If Environ(i) < "" Then
Cells(rw, 1) = Environ(i)
rw = rw + 1
End If
Next
Cells(rw + 1, 1) = rw
End Sub

I had

USERDOMAIN

I'm looking to see if any has a list, or know where I can
get a list of variables that I can use the Environ()
function on. Specifially I'm trying to log a users Domain
when they open the file. I've been able to get the
following variable so far:


User = Environ("USERNAME")
Machine = Environ("COMPUTERName")


Thanks,
