There may have been many different changes and forms of multi-tasking in
Windoze. you had 3.0 and 3.1 which were 16 bit, 3.11 and 3.11 WFWG which
were 32 bit, then you had the WIN-32 upgrade for all to run 32 bit apps,
then you had 95, then an upgrade to 95A.

I remember when we upgraded from either 3.0 or 3.1 to WFWG, we had a huge
change in operations and Windoze did not crash as often. We were using the
IBM to run it's own applications and as a VT terminal for a DEC VAX system
with a terminal emulator. Windoze crashed quite often when using this
emulator, then when we upgraded to WFWG and upgraded the emulator to the 32
bit version, we had far fewer crashes. So there were some serious changes
for the better, for a change. (We often swore that they were using a DEC PDP
11/70, but in reality they were using two VAX system together but it was
still sometimes very slow getting access to your files and programs. The DEC
was also running  System V AT&T UNIX at the same time as VMS.)
