Win95 does not have this, although NT does. Actualy, NT does *not* do that either. It is actualy nessecary to work 100% correctly that the Win16 applications run in the same VM. >2) OS/2 protects its kernel structures from its programs. Win95 > does not.

Not to mention, they are using *fast* and *mature* 16 bit code from over 10 years of improvement to speed up the kernel. If they do switch in the future (probibly in Win97 or Win98), it would be much slower. >3) Win95 does not pre-emptively multitask as soon as you run any > Win16 apps in it. OS/2 does.

That means it can run a windows subsystem for each application, and get pre-emp. multitasking! Win95 uses one windowing system that must act like the Win16 system to the Window 16 applications! >Tim. > -Dan Guisinger
