NT 3.1 Task Manager
The task manager is the same as the one in Windows 3.1

NT 3.1 Lock
Hitting Ctrl + Alt + Delete displays this message box, similar to later versions of Windows.

NT 3.1 Shutdown
Shutting down Windows NT 3.1, which is done from the File menu rather than by closing the Program Manager.

Conclusion:
Windows NT 3.1 is still inferior to OS/2 of the time, but it is better than ordinary 3.1 as it is 32-bit entirely and is thus it is much easier to do things in, plus it has all the 16-bit compatibility you would need.
