What was new in Windows 3.1 was a special handler for Ctrl+Alt+Del which tried to identify the program that was not responding and give you the opportunity to terminate it.
This worked 1% of the time. Because of the cooperative multitasking in win 3.1, 3.11, 95, 98 and Me the usual way out of this was reset or power off. Sometimes pressing the Ctrl+Alt+DEL will reboot the computer.
Windows 3.1 on a 386 used preemptive multitasking, yes, but only between Windows as a whole and other DOS programs you were running. Within Windows, win16 apps were cooperatively multitasked even on a 386.

Only Win 3.1 used cooperative multitasking (and only when running on a 286). All others used preemptive multitasking.

I stand corrected.
