You are under a mistaken impression; that is simply not true. On a 386
Windows intercepts direct screen writes and converts them to window
draws. On a 286 DOS app's won't run in a window. 

In the old days, Windows/286 could put programs that used the bios for
screen output in windows, and Windows/386 could put any program into a
window. The ability to intercept BIOS screen output functions on a 286
was eliminated from Win3 because it is so useless.
