I may be splitting hairs at this point, but I think we're both partly right; according to Wikipedia (https://en.wikipedia.org/wiki/Preemption_%28computing%29 https://en.wikipedia.org/wiki/Preemption_%28computing%29), Windows 95, 98 and ME had preemptive multitasking for 32 bit programs, but not 16 bit (which would have been the majority at the time of release of Win95). My confusion may come from remembering running multiple DOS and Windows programs at the same time in OS/2 with nary a hiccup and being able to tweak settings (such as RAM allotments).
