Question

According to wikipedia, there are lots of edition of Windows NT - Workstation, Server, Server Enterprise Edition, Terminal Server, Embedded... But how can I determine the edition of Windows NT in my box? The output of "winver" command is like

Micsoft(R) Windows NT(R)
Version 4.0 (Build 1381: Service Pack 6)
Copyright (C) 1981-1996 Microsoft Corp.
Revised Service Pack 6a

Answer 1

Doesn't it show the edition on the splash screen at bootup as below? (1)

Doesn't it say in the Start Menu as below? (2)

Open the registry and navigate to the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion, then look for a value called EditionID. If it's not there, then there should be another value (probably numeric) that can be looked up to find the edition. Or you can use a command-line tool to get the OS version info and look up the numbers in the chart. (3)

You could also try the SPCheck tool.
